Synthesis and Redox Properties of PNP Pincer Complexes Based on N-Methyl-4,4′-bipyridinium

Invited for the cover of this issue is the group of Yoshiaki Nishibayashi at The University of Tokyo, Japan. The cover image shows the synthesis of novel “metalloviologens” bearing PNP pincer ligands based on N‐methyl‐4,4′‐bipyridinium. These complexes are stable toward two steps of single electron transfer, where p‐quinoid‐type complexes play a key role. Our ultimate goal in this project is the construction of a stable redox system for efficient reduction of water and CO2 under photoirradiation...
