Abstract:
We measured Raman spectra in crystals of molecular donor–acceptor fullerene complexes $\{Me$($n$Pr$_{2}dtc$)$_{2}\}$ $\cdot$ (C$_{60}$)$_{2}$ ($Me$ = Ni, Cu, Pt). In the spectra of the $\{$Pt($n$Pr$_{2}dtc$)$_{2}\}$ $\cdot$ (C$_{60}$)$_{2}$ complex under prolonged irradiation with a laser with $\lambda$ = 532 nm, characteristic changes in the photopolymerization of fullerene are observed, associated with the splitting of degenerate phonon Hg modes and softening of Ag modes of the C$_{60}$ molecule. The kinetics of photopolymerization under conditions of weak irradiation at room temperature is studied. It was found that thermal destruction of the photopolymer with increasing temperature leads to a decrease in its concentration in the final photopolymerization product. The kinetics of thermal destruction is described by the Arrhenius equation, with the activation energy $E_A$ of (0.68 $\pm$ 0.03) eV; the dimers are destructed to a concentration of 1% within 15 min at $\sim$114$^{\circ}$C.
