Photogeneration of Singlet Molecular Oxygen (~1O_2, ~1Δ_(g))Using Monomeric and Aggregated Formsof Copper Tetra-4-(morpholine-4-yl)-tetra-5-(2-naphthoxy)phthalocyanine in Organic Solvents

摘要

Luminescence and chemical acceptors methods were used to study the photosensitized formation of singlet molecular oxygen (~1O_2, ~1Δ_(g)) by monomer and aggregated forms of copper tetra-4-(morpholine-4-yl)-tetra-5-(2-naphthoxy)phthalocyanine in benzene, benzene-fife, acetone, DMF, and pyridine. The values of ~1O_2 quantum yield were determined. The effectiveness of the ~1O_2 photoproduction was shown to be reduced due mainly to the aggregation of the copper phthalocyanine molecules.
