Raman study of the photopolymer formation in the {Pt(dbdtc)2}·C60 fullerene complex and the decomposition kinetics of the photo-oligomers

Abstract The photopolymer formation in the fullerene layers of the C 60 complex with platinum dibenzyldithiocarbamate is reported for the first time. The photo-oligomer peaks appear in the Raman spectra near the A g (2) mode of the C 60 molecule upon sample illumination with various laser wavelengths. The photo-oligomers are unstable upon heating and revert back to the C 60 monomeric state. The activation energy of the thermal decomposition, obtained from the Arrhenius dependence of the decay time constant on temperature, is (1.12 ± 0.11) eV and the photo-oligomers decompose at ∼130 °C, being more fragile than the crystalline polymers of C 60 .
