Abstract

Abstract : A new red light-excitable photosensitizer, Bi-rhodamine, was developed. Abstract : Bismuth-rhodamine (BiR) was developed as a new photosensitizer scaffold, and its photophysical properties were evaluated. BiR showed significant red-shifted absorption and emission compared with other xanthene-based photosensitizers, together with an efficient quantum yield for the generation of 1 O2 . BiR showed efficient cell-permeability as well as photo-triggered generation of 1 O2 in cells.
