Bis(terpyridine) Ru(iii) complex functionalized porous polycarbazole for visible-light driven chemical reactions

Abstract

The transformation of organic molecules into compounds of interest by the utilization of solar energy is an innovative approach that is attracting a lot of attention from material scientists. Introducing potent chelation sites onto a porous matrix is imperative for the purpose of effectively recycling cost-prohibitive catalysts, e.g., ruthenium and iridium complexes. To this end, bis(terpyridine) Ru(III) complex functionalized porous polycarbazoles, CPOP-32-Ru and CPOP-32-Ru′, were synthesized. Both polymers showed high thermal stability and efficient photocatalytic activities toward a range of important organic transformations, including amine coupling, aerobic hydroxylation of arylboronic acids, and selective oxidation of sulfides.
