Abstract

Abstract: As being irradiated with an intense UV radiation, photochemical dissociation of phtha-locyanine and M-phthalocyanines (M=Co, Mg, Cu, Zn, and Fe) is possible although phtha-locyanine compounds are usually considered to be rather stable. In this paper nitrogen-centered free radicals produced in photolysis of phthalocyanines were detected and investigated by means of spin trapping technigue and ESR spectroscopy.

Key words: photolysis, electron spin resonance, phthalocyanine, free radical
