The phase transitions induced by phutoescitatiun are observed in P3EIT-HT. The excitation spectra and intensity-dependence of the conversion efficiency suggest that the photo-induced phase transition in P3EIT-HT is not driven by the simple laser-heating process, but mediated by the photogenerated electron-hole pairs. A part of this work was supported partly by a Grant-in-Aid from the Ministry of Education, Science and Culture, Japan, and the New Energy and Industrial Technology Development Organization (NEDO).

N2 - Photo-induced phase transition is observed in poly(3-eicosyl)thiophenes containing head-to-tail couplings of alkyl sidegroups. Threshold and saturation in conversion efficiency of phase transition are found against variations of exciting photon density or photon energy. Observed behaviors indicate that the photo-induced phase transition is considered to be mediated by photogenerated electron-hole pairs which develop into clusters with local changes in bond structures on polymer backbone and sidegroups.
