テトラフェニルポルフィリン液晶における蛍光及び吸収スペクトルの相転移依存性と分子配向との相関

抄録

It was revealed that change of the absorption and fluorescence spectra through the mesomorphic phase transitions of a long-chain tetraphenylporphyrin is likely to reflect change of the molecular orientational order such as the presence or absence of molecular stacking structure. The fluorescence excitation spectra showed the evedence of band splittings in Q-band and two splitted peaks contibute to two fluorescence peaks at ca. 650 nm and ca. 720 nm in different way for each.
