Iridium(I)-Corrorin Complexes as Green-Light Photosensitizers for Singlet Oxygen

Abstract

Two mononuclear Ir(I)-corrorin complexes, FPh-Ir and Py-Ir, featuring peripheral κ 2 -N,N′ dipyrrin coordination, were structurally characterized and shown to combine good photostability with efficiently green-light-sensitized singlet oxygen generation (ΦΔ = 0.65-0.69 in CH3CN). TD-DFT supports a nearresonant S1→T3 intersystem-crossing pathway with appreciable spin-orbit coupling.
