Description
Summary:A new pincer ligand with N-heterocyclic carbene (NHC) and 4-pyridinol-derived rings supports ruthenium complexes for photocatalytic CO 2 reduction. The methoxy group on the pyridine ring offers unique catalysis advantages not seen with the unsubstituted analog. Our best catalyst offers selective CO formation, ∼250 turnover cycles, and a 40 h lifetime. New methoxy substituted CNC pincers form ruthenium catalysts that are robust and convert CO 2 to CO selectively using light energy.
