摘要: Mononuclear iridium(III) complexes [Ir(mppy)(tpy)X] (mppy = 4-methyl-2-phenylpyridine, X Cl, I) and binuclear analogues with various bis(2-phenylpyridin-4-yl) bridging ligands were synthesized characterized by their spectroscopic electrochemical properties. Kinetic measurements concerning the photocatalytic two electron reduction of CO2 to CO investigated in order determine influence intermolecular interactions between active centers. A detailed comparison monometallic bimetallic indicates an enhanced lifetime (TON) covalently linked complexes, causing increased overall conversion CO2. Additionally deactivation pathways catalysts are examined.
