- Abstract
A complex comprising one [Re(CO)3]+ unit and a phthalocyanine (Pc) ligand (Re1Pc) is shown to function as a photo‐induced CO‐releasing molecule (photoCORM) in the presence of O2 and a coordinative solvent under irradiation with red light, which can deeply penetrate living tissues. Transient absorption spectroscopic measurements indicate very short excited‐state lifetimes and ultrafast intersystem crossing for Re1Pc and Re2Pc, which contains two [Re(CO)3]+ units. The excited‐state properties are ascribed to efficient spin–orbit coupling and large Franck–Condon factors originating from the complexes' distorted structures, that is, unsymmetric coordination of [Re(CO)3]+ unit(s), one of which was confirmed by single‐crystal X‐ray analysis of a symmetrically substituted Pc with two [Re(CO)3]+ units. Re1Pc represents a promising red‐light‐driven photoCORM that can be applied in biological environments or therapeutic applications.
