Hybrid systems prepared by fixing a Re(I) complex and a dye on three types of TiO2 nanoparticles in two different ways commonly revealed persistent photocatalysis of the CO2 reduction to CO with no leveling-off tendency under visible-light irradiation in DMF, giving a turnover number of ≥435. The experimental process involved the reaction of 4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4Name: 4,4′-Bis(chloromethyl)-2,2′-bipyridine)
4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4) belongs to pyridine derivatives. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals. Name: 4,4′-Bis(chloromethyl)-2,2′-bipyridine
