We discovered an extremely suitable sacrificial electron donor, 1,3-dimethyl-2-(-hydroxyphenyl)-2,3-dihydro-1-benzo[]imidazole, for the selective photocatalytic reduction of CO to formic acid using a Ru(ii)-Ru(ii) supramolecular photocatalyst. The efficiency, durability, and rate of photocatalysis are significantly increased ( = 0.46, TON = 2766, TOF = 44.9 min) in comparison with those using 1,3-dimethyl-2-phenyl-2,3-dihydro-1-benzo[]imidazole or 1-benzyl-1,4-dihydronicotinamide.
