Abstract:

The quantum yield φΔ for sensitization of singlet molecular oxygen, O2(1Δg), by copper(II) tetracarboxyphthalocyanine (CuTCPc) in dimethyl sulphoxide was determined under stationary illumination, using diphenyl-isobenzofurane as chemical quencher. A constant value of φΔ = 0.16 ± 0.03 was obtained, independent of sensitizer concentration in the range 2-26 μM even though dimers and possibly oligomers are present at the highest concentrations. The monomer and the aggregates of CuTCPc physically quench O2(1Δg) with a nearly diffusional rate constant. © 1989.
