DNA photocleavage by an osmium(II) complex in the PDT window

Abstract

The extended π-delocalization of dppn (benzo[i]dipyrido[3,2-a:2,3-c]phenazine) results in a 3ππ* state as the lowest triplet excited state in [Os(bpy)2(dppn)]2+ (bpy = 2,2′-bipyridine), which generates a 1O2 quantum yield of 0.42. Together with its 3MLCT absorption, this new osmium complex shows efficient DNA cleavage under irradiation of λirr ≥ 645 nm.
