| Abstract(in English) | The thermochromic behaviors of poly(2, 5-dialkoxy-p-phenylene vinylelne)s have been studied. The temperature dependence of electrical and optical properties and the variation of properties with side chain length have been compared with those in poly(3-alkylthiophene)s. The band gap energy of ROPPVs increases gradually with increasing temperature. This tendency is different from PATs, and the difference can be tentatively interpreted in terms of the main chain structure. The photo luminescence intensity of ROPPVs decreases with increasing temperature. As this mechanism, we speculate the separation of the excited species due to the reduction of distance between polymer main chains and the enhancement of the overlap of π-electron with the twist of polymer main chains. The ionization potential of ROPPVs decreases slightly with increasing temperature. |
