π‐Extended Salphen Scaffolds Enable CO2 Electroreduction and Singlet Oxygen Generation

Chemistry – A European Journal, EarlyView.
New family of π‐extended salen ligands bearing phenylene bridge and tunable phenyl‐based substituents, and their corresponding boron difluoride complexes. Thanks to the extended π‐delocalization over the molecule, the ligands themselves show promising results in electrochemical CO2 reduction to CO, while the complexes act as efficient photosensitizers ...
