Abstract

Time resolved photobleaching studies of titanyl phthalocyanines with different crystalline structures are reported. Strong photobleaching of the edge components of the complex Q absorption band and much weaker in the center of the band was found to be a general feature of crystalline and amorphous structures. Such behavior was explained by the ultrafast excitation transfer between different molecular species.
