Abstract
Phthalocyanines are well known to provide organic photoconductors of high photoelectric conversion efficiencies. In order to elucidate the mechanism which gives rise to this high efficiency, we need to know the characters of these materials in the excited states. Previously, we reported time-resolved IR (TRIR) absorption spectra of τ-form metal-free phthalocyanine (τ-H2PC) fine particles using a newly developed IR spectrometer with μs time-resolution [1]. We assigned the observed TRIR bands to the triplet exciton of τ-H2PC. In the present study, we further improved our TRIR spectrometer (detection limit of absorbance change down to 3x10-7) and reexamined the TRIR absorption of H2PC.
