Formation of singlet oxygen in the system tris(bipyridine)ruthenium(II)-dimethyldioxirane
Abstract
Decomposition of dimethyldioxirane in the presence of tris(bipyridine)ruthenium(II) complex (RuII) is accompanied by chemi-luminescence (CL) in the infrared spectrum region (1270 nm) due to the formation of singlet oxygen; reaction between RuIII and superoxide ion, which is formed in this process via a sequence of electron-transfer reactions, is assumed to be a CL step.
