Nickel and cobalt complexes of 14-membered tetraazamacrocycles mediate electron transfer and produce CO in the photochemical reduction of CO2. Two integrated systems for the CO2 reduction are discussed: (1) photophysical properties of bifunctional supramolecules, Ru(bpy)2(bpy-L10M)4+ (bpy = 2,2'-bipyridine, bpy-L10 = 1-(2,2'-bipyridin-6-ylmethyl)-1, 4,8,11-tetraazacyclotetradecane, M = H2, Ni) and its limitation as a photocatalyst; (2) advantages of multimolecular system with p-terphenyl as a photosensitizer, a cobalt macrocycle as an electron mediator, and a tertiary amine as a sacrificial electron donor.
