Film formation: A general strategy for synthesizing thin films of π-conjugated microporous polymers is described (see picture). Using a thiophene-based high-throughput electropolymerization it was possible to control the thickness of the films. The π-conjugated microporous polymers are shown to be outstanding conductors with a high carrier mobility and photoactive layers for efficient conversion of photoenergy.

The efficiency of perovskite solar cells (PSCs) has been improved from 9.7 to 19.3%, with the highest value of 20.1% achieved in 2014. Such a high photovoltaic performance can be attributed to optically high absorption characteristics and balanced charge transport properties with long diffusion lengths of the hybrid lead halide perovskite materials. In this review, some fundamental details of hybrid lead iodide perovskite materials, various fabrication techniques and device structures are described, aiming for a better understanding of these materials and thus highly efficient PSC devices. In addition, some advantages and open issues are discussed here to outline the prospects and challenges of using perovskites in commercial photovoltaic devices.

Record SMM POM: A new class of polyoxometalate (POM) containing 3d–4f and 4f aggregates encapsulated by [A-α-GeW₉O₃₄]¹⁰⁻ ligands to give [Dy₃₀Co₈Ge₁₂W₁₀₈O₄₀₈(OH)₄₂(OH₂)₃₀]⁵⁶⁻ is described. This hybrid with single-molecule magnet (SMM) behavior contains the largest number of 4f ions of any POM reported to date and is the first to incorporate two different 3d–4f and 4f coordination cluster assemblies within same POM framework.

Blends of two chemically interacting copolymers bridge the gap from ultra- (UF) to nanofiltration (NF) as such membranes with pore sizes below 5 nm have been synthesized without post-treatment. Simulations of the membrane formation process by dissipative particle dynamics were used to explain the dramatic observed pore size reduction combined with an increase in water flux.
