Inserting Porphyrin Quantum Dots in Bottom-Up Synthesized Graphene Nanoribbons
Abstract
Diels–Alder copolymerization of tetraphenylcyclopentadienone, a precursor for cove graphene nanoribbons (cGNRs), with bifunctional porphyrins yields defined nanostructures comprised of a single cGNR-porphyrin-cGNR heterojunction within each ribbon. 13C NMR labeling and high-resolution mass spectrometry of solubilized polymer intermediates indicates that every porphyrin is covalently linked to two extended segments of cGNRs. UV/Vis absorption and fluorescence emission spectroscopy reveal a strong electronic correlation between the porphyrin and the adjacent cGNR segments that can be attenuated through reversible metalation of the porphyrin core. This versatile bottom-up synthetic strategy provides access to structurally well-defined, functional GNR-quantum dot-GNR heterostructures within a single graphene nanoribbon.
The bottom-up solution-based synthesis and selective fractionation of graphene nanoribbon-porphyrin-graphene nanoribbon heterostructures is reported. Absorption and fluorescence spectroscopy reveal a strong coupling between the graphene nanoribbon and the central porphyrin quantum dot.

Decacene: On-Surface Generation
Decathletes: Combined efforts of organic synthesis and on-surface chemistry have led to the preparation of decacene for the first time. An iterative sequence of aryne cycloadditions was used to synthesize stable tetraepoxy precursors which were reduced on Au(111) to obtain unprecedented decacene as visualized by scanning tunneling microscopy (STM).

Synthesis and the Nobel Prize in Chemistry
Synthesis and the Nobel Prize in Chemistry
Nature Chemistry, Published online: 22 September 2017; doi:10.1038/nchem.2864
The question often arises as to who may have deserved a Nobel Prize but was not awarded one. Rarely is this discussion extended to who should have received more than one Nobel Prize, but in the field of organic synthesis there are some compelling candidates.
