The built‐in electric field of polymer semiconductors determines its interfacial space charge and band bending to separate electrons and holes. In their Research Article (e202318224), Yi‐Jing Chen, Zhi‐Xing Wu, Jing‐Xin Jian et al. report three perylene diimide (PDI) polymers with different molecular orientations of ortho‐, meta‐ and para‐phenylenediamine linkers. By regulating the dipole moment of...
Amide sind in der biologischen und medizinischen Chemie allgegenwärtig. In ihrem Forschungsartikel (e202112668) berichten Jiannan Zhao et al. über eine “Oxidations‐Reduktions‐Kondensationsreaktion” mittels PPh3 als organischem Reduktionsmittel. Das synergistische Zusammenspiel zwischen einem Co(III)‐ und einem Ir(III)‐Photoredoxkatalysator ermöglicht die Bildung von Acyloxyphosphonium‐Spezies, die...
