✦ Synopsis

Charge carrier photogeneration in titanyl phthalocyanine was investigated by means of fluorescence and photocurrent measurements, under sample excitation by two time-separated ultrashort light pulses. Exciton-exciton annihilation was employed to obtain information on the time course of the fluorescence and generation processes. Charge carriers were found to be generated during only a short time interval after the exciton was created. This interval is much shorter than the fluorescence state lifetime.

Long-lived triplet excitons are generated by laser excitation of a zinc porphyrin Langmuir-Blodgett film. The transient T-T spectrum is similar to that obtained in the liquid phase and the triplet excitons disappear with second-order kinetics by T-T annihilation. Their half-life varies from 1 lo? 10
