cis-Dipyridyl porphyrin-based multicomponent organoplatinum(ii) bismetallacycles for photocatalytic oxidation

Abstract

Three porphyrin-based bismetallacycles are prepared via multi-component metal-coordination-driven self-assembly. Owing to different tetracarboxylic ligands in their structures, they show distinct coordination geometries and stacking modes, which inhibit the self-aggregation of porphyrin and offer improved singlet oxygen generation efficiency. These bismetallacycles are successfully used for the photooxidation of methyl(phenyl)sulfane, showing their potential applications toward photocatalysis.
