Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The spectral-luminescence properties of indolo[2,3-b]quinoxaline, which at 77 °K has fluorescence and phosphorescence of the ππ* type, were investigated. Retarded fluorescence and nonexponential quenching of the phosphorescence were observed; this is explained by photochemical processes with subsequent recombination luminescence.
