Abstract
Dissymmetrical perylene-3,4,9,10-tetracarboxydiimide building block (PDI) was used to obtain the dyads with fullerene (PDI-C60) and tetrathiafulvalene (PDI-TTF). Photoinduced electron transfer in these dyads was investigated with light-induced electron spin resonance (LESR) spectroscopy. The LESR signals of the samples in CHCl3 solutions were recorded in the dark and under light illumination, at room temperature and at about 80 K. It was stated that the LESR signal increases stepwise with the incident light and decreases slowly when the light is switched off. The photogeneration of PDI+, TTF− and C60− ion-radicals was observed and analyzed. The principal parameters of the LESR lines of the ion-radicals are determined.
