Fragmentation of Manganese Phthalocyanine Films by Laser Radiation

Abstract

The study of MPc is motivated by the prospects of the creation of optoelectronic devices that operate in the visible light range. The combination of their physico-chemical and semiconducting properties makes them the promising material for cheap thermo-stable organic optoelectronic devices. In connection with this the question of degradation of macrocyclic phthalocyanine when exposed by harsh environments, in particular laser radiation, is very actual The studies of MPc's degradation under electron beam and pyrolysis is well Pyrolysis of polymeric cobalt phthalocyanine [ was carried out at 500 - 1000°C, the mass spectra were recorded across 0.6 - 3.6 minutes. The proposed mechanism of initial thermal degradation leads to the isoindole derivatives The paper presents results of a study of fragmentation of manganese phthalocyanine films that are in the condensed state on a solid surface by means of laser irradiation (λ=532 nm), i.e. in the spectral region of absorption
