Abstract

Two mononuclear Ir(I)–corrorin complexes, FPh-Ir and Py-Ir, featuring peripheral κ2-N,N′ dipyrrin coordination, were structurally characterized and shown to efficiently photosensitize singlet oxygen under green light (ΦΔ = 0.65–0.69 in CH3CN). TD-DFT supports a near-resonant S1 → T3 intersystem-crossing pathway with appreciable spin–orbit coupling.
