摘要：

Triplet states of oligothiophenes and C-60 were excited by a pulsed laser light using a Nd:YAG laser. The finestructure values D, E of different endcapped oligothiophenes (EC3T, EC4T, and EC5T) were determined from pulsed EPR-spectra. Time resolution was applied to study the kinetics and relaxation times. A photoinduced electron transfer from EC4T to C-60 in liquid solutions was investigated in detail. Fourier transform of the free induction decays results in spectra of the transient triplet state and of the transient C-60 monoradical anion. Electron transfer rates were deduced from the observed triplet quenching rates at different temperatures.
