PB10 液晶性アゾベンゼンブロック共重合体の光配向と実空間観察による配向過程の考察(化学・材料,ポスター発表,2012年日本液晶学会討論会)

抄録

We synthesized diblock copolymers consisting of poly(buthyl methacrylate) (PBMA) unit and azobenzene (Az)-containing poly(methacrylate) by atom transfer radical polymerization method. The spin-coating films of PBMA-b-PAz were irradiated with polarized visible light at LC temperature. Orientation of azobenzene chromophore were investigated by polarization spectroscopy. The resulting films exhibited monoaxial orientation of microphase separated structure in thin films. We observed the cross-sectional profiles of the thin films by TEM. We will discuss the photoorientation process of microphase separated structure.
