Abstract
- The pressure-assisted photopolymerization in the fullerene complex {Cd(dedtc)2} 2·C60 (fullerene complex with cadmium diethyldithiocarbamate) observed in the pressure region between 2.24 and 5.99 GPa was studied in detail. After a phase transition near ~ 2 GPa, the Raman spectra exhibit time-dependent changes under prolonged laser illumination regarding the appearance of new peaks in the frequency region of the A g (2) mode of the C60 monomer. These peaks are related to the fullerene oligomers with a different number of sp3-like coordinated carbon atoms per molecular cage. The polymer content increases with the laser power density and exposure time, while for a fixed laser power, its saturated value is independent of pressure. Outside the pressure range 2.24 5.99 GPa, photopolymerization is suppressed.
