Aqueous emissive cyclometalated iridium photoreductants: synthesis, computational analysis and the photocatalytic reduction of 4-nitrophenol

Abstract

Herein, we present luminescent mononuclear iridium complexes [1]3+ - [4]3+ using a NEt3-appended C^N chelating benzimidazole (L1 – L4) and a semi-flexible phenanthroline-pyrazine-based (phpy) ligands exhibiting photocatalytic reduction of 4-nitrophenol...
