We have synthesized three kinds of azobenzene compounds having an acrylate qroup. The acrylate group was attached to para position of azobenzene group through an ester bonding. The other para positon of azobenzene qroup was substituted by methoxy, cyano, and nitro groups. A diacrylate monomer was also synthesized. All compounds showed a nematic phase as a liquid crystalline phase. Eutectic blends consisting of the azobenzene compounds and the diacrylate compound were prepared. The eutectic blends were placed in a cell. The cell consisted of two parallel ITO-coated glass plates with spacing of 5 μm, and was subjected to a rubbing treatment on the ITO electrodes prior to inject the eutectic blends. The thermal bulk polymerization of the eutectic blends was performed in an constant electric field. We will discuss the molecular orientation in films obtained by thermal bulk polymerization.
