Based on a chiral donor–acceptor copolymerization strategy, two pairs of chiral nonconjugated TADF polymers with low ΔE
ST values and high PLQYs were constructed. The corresponding solution-processed CP-OLEDs exhibited intense CPEL signals and high device efficiencies with an EQEmax of up to 22.1 %.
Abstract
A strategy of chiral donor–acceptor copolymerization is proposed to develop chiral nonconjugated polymers with thermally activated delayed fluorescence (TADF). Based on this strategy, two pairs of chiral polymers (R,R)-/(S,S)-pTpAcDPS and (R,R)-/(S,S)-pTpAcBP were synthesized. The alternating copolymerization of the chiral donors and acceptors could effectively separate the frontier molecular orbitals, which made the polymers show small ΔE
ST of 0.01–0.03 eV and efficient TADF properties. Moreover, the polymers also showed the quantum yield of up to 92 % and the circularly polarized luminescence. The solution-processed circularly polarized organic light-emitting diodes showed circularly polarized electroluminescence signals with high external quantum efficiencies of up to 22.1 % and maximum luminance of up to 34350 cd m−2. This is the first report of CP-OLEDs based on chiral TADF polymer, which provides a useful and valuable guidance for the development of high-efficiency CPEL polymers.

Next-generation, base-activated latent sulfinate reagents have been successfully developed for use in the construction of heteroaromatic frameworks, such as 2-arylpyridines. Under Pd-catalyzed conditions, these species unmask to give the sulfinate in situ, which then undergoes efficient desulfinative cross-coupling with an array of (hetero)aryl halides.
Abstract
Heteroaromatic sulfinates are effective nucleophilic reagents in Pd0-catalyzed cross-coupling reactions with aryl halides. However, metal sulfinate salts can be challenging to purify, solubilize in reaction media, and are not tolerant to multi-step transformations. Here we introduce base-activated, latent sulfinate reagents: β-nitrile and β-ester sulfones. We show that under the cross-coupling conditions, these species generate the sulfinate salt in situ, which then undergo efficient palladium-catalyzed desulfinative cross-coupling with (hetero)aryl bromides to deliver a broad range of biaryls. These latent sulfinate reagents have proven to be stable through multi-step substrate elaboration, and amenable to scale-up.

An organic long persistent luminescence (OLPL) system based on in situ generated ionic pairs with CuI centers is proposed and demonstrated. Intermediates are proposed and verified through a series of carefully designed experiments. The afterglow of corresponding blends can last more than 3 hours, thus this mechanism is the first to incorporate CuI ions in OLPL systems.
Abstract
Recent development of most organic long persistent luminescence (OLPL) systems employed binary or tertiary doping. However, the design strategies towards OLPL materials with hour-long afterglow duration are still quite limited. Here, we propose a novel OLPL system through melt-casting method with 0.1 mol % of CuI complexes: 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl BINAP-CuX (X=Cl, Br and I) doped into the triphenylphosphine (TPP) host. The charge separation was initiated prior to excitation through host coordination with CuI complexes, resulting in semi-free halogen ions and in situ generated CuI cations, which forms TPP + BINAP-CuX ionic pairs and subsequently ionic solids. The OLPL lifetime can be readily modulated by different halogen atoms and the afterglow can last up to more than 3 hours perceivable to human eyes. This is a rare example of OLPL initiated through host-guest coordination that could potentially expand the definition of OLPL systems and design strategies.

The photodegradation pathway of acceptor–donor–acceptor-type non-fullerene acceptors with 1,1-dicyanomethylene-3-indanone termini for organic photovoltaics was elucidated as a 6-e electrocyclic reaction between the dicyanomethylene unit and the thiophene ring, followed by a 1,5-sigmatropic hydride shift (see picture). This photoisomerization was accelerated under inert conditions, as explained by DFT calculations predicting a triplet-mediated reaction pathway.
Abstract
Herein, we elucidate the photodegradation pathway of A-D-A-type non-fullerene acceptors for organic photovoltaics. Using IT-4F as a benchmark example, we isolated the photoproducts and proved them isomers of IT-4F formed by a 6-e electrocyclic reaction between the dicyanomethylene unit and the thiophene ring, followed by a 1,5-sigmatropic hydride shift. This photoisomerization was accelerated under inert conditions, as explained by DFT calculations predicting a triplet-mediated reaction path (quenchable by oxygen). Adding controlled amounts of the photoproduct P1 to PM6:IT-4F bulk heterojunction cells led to a progressive decrease in photocurrent and fill factor attributed to its poor absorption and charge transport properties. The reaction is a general photodegradation pathway for a series of A-D-A molecules with 1,1-dicyanomethylene-3-indanone termini, and its rate varies with the structure of the donor and acceptor moiety.

Hole-transport-layer (HTL) free tin perovskite solar cells would solve the stability issue caused by the unstable organic HTL. Formamidinium tin iodide doped with heterogeneous ammonium salts can form an upward band-bending structure to selectively extract the hole in the HTL-free cells. An efficiency of over 10% with reliable light-soaking and thermal stability can be achieved for the cells.
Abstract
Lead-free tin perovskite solar cells (PSCs) have emerged as a promising candidate toward high-performance and eco-friendly photovoltaic technology with great potential for future application. However, tin PSCs with over 10% efficiency usually feature an organic hole transport layer (HTL) at the illumination side that may induce device degradation during long-term operation. Removing the unstable organic HTL is an important way to solve these stability issues, but the efficiency of HTL-free tin PSCs is still much lower than that of the completed cells. Herein, it is demonstrated that formamidinium tin iodide doped with heterogeneous ammonium salts can form an upward band-bending structure to selectively extract the hole in the HTL-free devices. By using this band-bending structure, a promising efficiency of over 10% is first achieved for the lead-free PSCs with a HTL-free structure. More importantly, the optimized cell is highly stable, keeping 95% and 90% of the initial efficiency after continuous light soaking for 40 days and 80 °C annealing for 300 h, respectively. This work paves a route toward the development of efficient, eco-friendly, and highly stable perovskite photovoltaics.

A series of dual-cationic fluorophores with N+ and P+ group are prepared as organelle-targeting antitumor photosensitizers (PSs) with aggregation-induced emission activity. These PSs can selectively accumulate at the mitochondria or lysosomes with both dark- and photo-cytotoxicity, thus demonstrating an excellent killing effect on cancer cells and efficient inhibition of tumor growth in living mice.
Abstract
The development of anticancer therapy is significant to human health but remains a huge challenge. Photodynamic therapy (PDT), inducing the synergistic mitochondrial dysfunction in cancer cells is a promising approach but suffer from the low efficiency in hypoxic microenvironment and deep-seated tumors. Herein, to improve the outcomes of PDT for cancer treatment, a series of red fluorophores consisting of dual-cationic triphenylphosphonium-alkylated pyridinium and (substituted) triphenylamine are prepared as organelle-targeting antitumor photosensitizers (PSs) with aggregation-induced emission characteristics. These PSs can selectively accumulate at the mitochondria or lysosomes of cancer cells with both dark- and photo-cytotoxicity, making them possess excellent killing effect on cancer cells and efficient inhibition of tumor growth in living mice. This study brings about new insight into the development of powerful cancer treatment.

A new kind of tunable photoresponsive material from photoactivated phosphorescence to photochromism is developed through doping triarylamine derivatives with different aryl substituents into a poly(methyl methacrylate) (PMMA) matrix. Accordingly, they are conveniently applied in rewritable photopatterning, anticounterfeiting, information encryption, and sunglasses.
Abstract
Photoresponsive materials have drawn much attention and are widely applied in daily life for their reversible changes in luminous color or appearance color under light irradiation. In this work, a new photoresponsive system based on triarylamine derivatives is developed. With the changed aryl substituents, adjustable photoresponsive properties, including photoactivated phosphorescence and photochromism after being dispersed into the poly(methyl methacrylate) (PMMA) matrix, are demonstrated. According to the theoretical calculations and experimental data, the competition between the formations of triplet excitons and cationic radicals under photoirradiation should be the main reason for their different photoresponsive properties. Excitingly, the applications of rewritable photopatterning, anticounterfeiting, information encryption, and decryption are realized conveniently, in addition to the successful model of sunglasses to protect eyes away from ultraviolet radiation and strong light in the sunlight. These studies present a simple and efficient design strategy for the development of photoresponsive materials on modulating the phosphorescence and photochromic property.

A Cu(I) complex with an extremely fast reverse intersystem crossing rate is demonstrated as a thermally activated delayed fluorescence sensitizer for a both conventional fluorescent and multi-resonance thermally activated delayed fluorescence (MR-TADF) emitter. The resulting fluorescent guest-based device shows very low efficiency roll-off at high luminance, while the MR-TADF OLED realizes a record-high EQE of 26.5% with a narrowband emission peaking at 566 nm and a full-width at half maximum of 46 nm.
Abstract
Organic light-emitting diodes (OLEDs) utilizing purely organic thermally activated delayed fluorescence (TADF) sensitizers have recently achieved high efficiencies and narrow-band emissions. However, these devices still face intractable challenges of severe efficiency roll-off at practical luminance and finite operational lifetime. Herein, a carbene-Cu(I)-amide complex, (MAC*)Cu(Cz), is demonstrated as a TADF sensitizer for both fluorescent and TADF OLEDs. The (MAC*)Cu(Cz)-sensitized fluorescent OLED not only achieves a high external quantum efficiency (EQE) of 14.6% with an extremely low efficiency roll-off of 12% at the high luminance of 10 000 nits, but also delivers a 15 times longer operational lifetime than that of the non-sensitized reference device. More importantly, utilizing the (MAC*)Cu(Cz) sensitizer in the multi-resonance (MR) TADF OLED results in a record-high EQE of 26.5% together with a full-width at half maximum of 46 nm and an emission peak at 566 nm. This value is the state-of-the-art efficiency for yellow-emitting MR-TADF OLEDs. The photophysical analysis proved that the fast reverse intersystem crossing process of (MAC*)Cu(Cz) is the key factor to suppress triplet exciton involved quenching at high luminance. This finding firstly demonstrates the use of Cu(I) complex as an efficient TADF sensitizer and paves the way for practical applications of TADF sensitized OLEDs.

The very recent advances in organic field-effect transistors-based photonic synapses are summarized from the perspectives of functional materials, configurations, and innovative applications.
Abstract
Photonic artificial synapses-based neuromorphic computing systems have been regarded as promising candidates for replacing von Neumann-based computing systems due to the high bandwidth, ultrafast signal transmission, low energy consumption, and wireless communication. Although significant progress has been made in developing varied device structures for synaptic emulation, organic field-effect transistors (OFETs) hold the compelling advantages of facile preparation, liable integration, and versatile structures. As a powerful and effective platform for photonic synapses, OFETs can fulfill not only the simulation of simple synaptic functions, but also complex photoelectric dual modulation and simulation of the visual system. Herein, an overview of OFET-based photonic synapses, including functional materials, device configurations, and innovative applications is provided. Meanwhile, rules for selecting materials, mechanism of photoelectric conversion, and fabrication techniques of devices are also highlighted. Finally, challenges and opportunities are all discussed, providing solid guidance for multilevel memory, multi-functional tandem artificial neural system, and artificial intelligence.

Two fused bithiophene imide dimer-based n-type polymers bearing hydrophilic branched methyl end-capped glycol side chains were developed, showing a high degree of backbone planarity, favorable polymer chain packing orientation, and substantial electrochemical doping efficiency. As a result, the f-BTI2TEG-FT-based organic electrochemical transistors (OECTs) deliver a record-high geometry-normalized transconductance of 4.60 S cm−1.
Abstract
The development of n-type organic electrochemical transistors (OECTs) lags far behind their p-type counterparts. In order to address this dilemma, we report here two new fused bithiophene imide dimer (f-BTI2)-based n-type polymers with a branched methyl end-capped glycol side chain, which exhibit good solubility, low-lying LUMO energy levels, favorable polymer chain orientation, and efficient ion transport property, thus yielding a remarkable OECT electron mobility (μ
e) of up to ≈10−2 cm2 V−1 s−1 and volumetric capacitance (C*) as high as 443 F cm−3, simultaneously. As a result, the f-BTI2TEG-FT-based OECTs deliver a record-high maximum geometry-normalized transconductance of 4.60 S cm−1 and a maximum μC* product of 15.2 F cm−1 V−1 s−1. The μC* figure of merit is more than one order of magnitude higher than that of the state-of-the-art n-type OECTs. The emergence of f-BTI2TEG-FT brings a new paradigm for developing high-performance n-type polymers for low-power OECT applications.

The Förster resonance energy transfer between two molecules can facilitate the high-lying reverse intersystem crossing process in aggregation-induced emission and hybridized local and charge-transfer hosts, thereby reducing the loss from T

−1 state and improving exciton utilization, and finally realizing the efficiency breakthrough of blue fluorescence organic light-emitting diodes.
Abstract
Aggregation-induced emission (AIE) and hybridized local and charge-transfer (HLCT) materials are two kinds of promising electroluminescence systems for the fabrication of high-efficiency organic light-emitting diodes (OLEDs) by harnessing “hot excitons” at the high-lying triplet exciton states (T
n
, n ≥ 2). Nonetheless, the efficiency of the resulting OLEDs did not meet expectations due to the possible loss of T

−1. Herein, experimental results and theoretical calculations demonstrate the “hot exciton” process between the high-lying triplet state T3 and the lowest excited singlet state S1 in an AIE material 4⁗-(diphenylamino)-2″,5″-diphenyl-[1,1″:4′,1″:4″,1′″:4′″,1⁗-quinquephenyl]-4-carbonitrile (TPB-PAPC) and it is found that the Förster resonance energy transfer (FRET) between two molecules can facilitate the “hot exciton” process and inhibit the T3→T2 loss by doping a blue fluorescent emitter in TPB-PAPC. Finally, the doped TPB-PAPC blue OLEDs achieve a maximum external quantum efficiency (EQEmax) of 9.0% with a small efficiency roll-off. Furthermore, doping the blue fluorescent emitter in a HLCT material 2-(4-(10-(3-(9H-carbazol-9-yl)phenyl)anthracen-9-yl)phenyl)-1-phenyl-1H-phenanthro[9,10-d] imidazole (PAC) is used as the emission layer, and the resulting blue OLEDs exhibit an EQEmax of 17.4%, realizing the efficiency breakthrough of blue fluorescence OLEDs. This work establishes a physical insight in the design of high-performance “hot exciton” molecules and the fabrication of high-performance blue fluorescence OLEDs.

The novel structurally defined and covalently linked donor–acceptor dyad 4 is implemented into single-material organic solar cells as the essential ambipolar and photoactive layer. The combination of an oligothiophene donor and PC71BM fullerene as acceptor not only leads to enhanced 5.34% power conversion efficiency, but also to impressive long-term stability after 750 hours (one month) of continuous illumination.
Abstract
A novel donor–acceptor dyad, 4, in which the conjugated oligothiophene donor is covalently connected to fullerene PC71BM by a flexible alkyl ester linker, is synthesized and applied as photoactive layer in solution-processed single-material organic solar cells (SMOSCs). Excellent photovoltaic performance, including a high short-circuit current density (J
SC) of 13.56 mA cm−2, is achieved, leading to a power conversion efficiency of 5.34% in an inverted cell architecture, which is substantially increased compared to other molecular single materials. Furthermore, dyad 4-based SMOSCs display excellent stability maintaining 96% of the initial performance after 750 h (one month) of continuous illumination and operation under simulated AM 1.5G irradiation. These results will strengthen the rational molecular design to further develop SMOSCs for potential industrial application.

By designing new donor/acceptor materials and combining a ternary blending strategy, a maximum power conversion efficiency (PCE) of 19.0% (certified value of 18.7%) in single-junction organic photovoltaic (OPV) cells is achieved. It is demonstrated that finely tuning the light utilization and photophysical processes of the active layer has great potential for further improving the PCEs of OPV cells.
Abstract
Improving power conversion efficiency (PCE) is important for broadening the applications of organic photovoltaic (OPV) cells. Here, a maximum PCE of 19.0% (certified value of 18.7%) is achieved in single-junction OPV cells by combining material design with a ternary blending strategy. An active layer comprising a new wide-bandgap polymer donor named PBQx-TF and a new low-bandgap non-fullerene acceptor (NFA) named eC9-2Cl is rationally designed. With optimized light utilization, the resulting binary cell exhibits a good PCE of 17.7%. An NFA F-BTA3 is then added to the active layer as a third component to simultaneously improve the photovoltaic parameters. The improved light unitization, cascaded energy level alignment, and enhanced intermolecular packing result in open-circuit voltage of 0.879 V, short-circuit current density of 26.7 mA cm−2, and fill factor of 0.809. This study demonstrates that further improvement of PCEs of high-performance OPV cells requires fine tuning of the electronic structures and morphologies of the active layers.
