Abstract

Picosecond time-resolved resonance Raman (TR3) spectroscopy was applied to investigate the photoinduced electron transfer in dyades employing phenothiazine as electron donor and pyrene as electron acceptor. Because the vibrational spectra of the pyrene excited state and the pyrene radical anion exhibit pronounced differences, the occurrence of photoinduced electron transfer can be proven beyond doubt for those derivatives, for which estimates yield DeltaG(et) < 0.
