自己組織化による界面活性剤-酸化黒鉛層間化合物中のナノ空間へのアゾベンゼンの導入

抄録

Azobenzene and p-aminoazobenzene molecules were introduced into nano-space of various surfactant-intercalated graphite oxides via self-assembly. The composition of surfactantintercalated graphite oxides saturated by azobenzene molecules were determined from their X-ray diffraction data. The azobenzene contents increased with the increase of alkyl chain length of surfactants, while they were almost independent of surfactant contents in the intercalation compounds. Azobenzene molecules were dispersed in the nanospace of surfactantintercalated graphite oxide without crystalization. On the other hand, blue shift of absorption peak due to p-aminoazobenzene molecules suggested that they formed H-aggregate when their concentration was high.
