  • Oxidative C–H/N–H cross-coupling is a convenient method to construct C–N bonds, however this is rarely achieved in a sustainable manner. Here, the authors show an oxidant-free electrochemical C–H/N–H cross-coupling between electron-rich arenes and diarylamines to afford triarylamines with exclusive para-selectivity.

  • Piracetam improves wide-bandgap perovskite crystallinity and uniformity, enabling monolithic all-perovskite tandem solar cells with efficiencies of 28.71% (0.07 cm2) and 28.20% (1.02 cm2), ensuring minimal efficiency loss during scale-up.

  • Ligands and additives are often utilized to stabilize low-valent catalytic metal species experimentally, while their role in suppressing metal deposition has been less studied. Here, the authors report an on-cycle mechanism for CoCl2bpy2 catalyzed Negishi-type cross-coupling describing a full catalytic cycle for this reaction using multiple spectroscopic studies.

  • C14-functionalized steroids are pharmaceutically valuable, but their synthesis is challenging. Now a chemoenzymatic route is reported featuring a key biocatalytic C14α-hydroxylation, enabled by protein engineering of a C14α-hydroxylase (CYP14A) from Cochliobolus lunatus. Dehydration and olefin functionalization of the biocatalytic reaction products provides C14-functionalized steroids.

  • Defect-assisted nonradiative recombination and carrier aggregation at the interface hinder the potential of perovskites as emitter for light-emitting diodes. Here, Fang et al. achieve an external quantum efficiency of 24.1% by combining multidimensional perovskite with cascade conduction bands.

  • Enriching the chemical space of polycyclic heterocycles is of high value in chemical biology. Here, the authors report an electrooxidative protocol for the regioselective dearomative annulation of indoles and benzofurans under undivided cell conditions and obtain five- to eight-membered fused heterocycles.

  • Non-viral vectors are important for transfection but can be limited in the uptake, protection and release of ssDNA. Here, the authors report on the design of metal-organic-framework vectors with precisely controlled pore geometry and demonstrate the vector in the transfection of immune cells.
