Surprisingly, photo-driven experiments for the CO<sub>2<\/sub> reduction showed that this complex can undergo a photoinduced electron transfer with a sacrificial electron donor and accumulate electrons on the diimine backbone. Photo-driven experiments in a CO<sub>2<\/sub> atmosphere revealed that this complex can not only act as a photosensitizer, when combined with an Fe(III)-porphyrin, but can also selectively produce CO from CO<sub>2<\/sub>.
