Abstract

Potoconductive polymer not only is now utilized as transport materials of photosignal but also is a prospective material as photon-electron converter and charge transporter in organic solar cell. Polydiacetylene film has a potential as photoinformation transporter because of its one-dimensional high mobility based on π-conjugation along polymer chain and regionregularity of polymer crystal. It is, therefore, desired to elucidate the photocarrier generation mechanism. In this research, we have prepared oriented polymer film of 16-di(N-carbazolyl)-2,4-hexadiyne (DCHD) using an epitaxial growth technique on poly(tetrafluoreethylene) film aligned by a friction deposition method. The anisotropy of generation process and spin dynamic of the photocarrier was examined from the electric and magnetic field effects on photocurrent.
