Abstract

Relaxation dynamics from a higher triplet excited state in α-sexithienyl (hereafter abbreviated as 6T) film was investigated by double-pulse excitation spectroscopy. Very rapid formation (within 1 ps) of the lowest singlet excited state and an intermolecular ion-pair state were observed. The mechanism of this rapid conversion process from a higher electronic excited state was discussed.
