摘要: A 2,2′-bipyridyl-containing poly(arylene-ethynylene)-alt-poly(arylene-vinylene) polymer, acting as a light-harvesting ligand system, was synthesized and coupled to an organometallic rhodium complex designed for photocatalytic NAD+/NADH reduction. The material, which absorbs over wide spectral range, characterized by using various analytical techniques, confirming its chemical structure properties. dielectric function of the material determined from spectroscopic ellipsometry measurements. Photocatalytic reduction nucleotide redox cofactors under visible light irradiation (390–650 nm) performed is discussed in detail. new metal-containing polymer can be used cover large surface areas (e.g. glass beads) and, due this immobilization step, easily separated reaction solution after photolysis. Because high stability, polymer-based catalyst system repeatedly different conditions (photo)chemical NAD+. Wit...
