Zhu, Gang; Wang, Fei; Liu, Wenjie; Gong, Xinjian; Geng, Pengfei; Gao, Zhenwei; Wang, Yinghan published the artcile< Synthesis of photosensitive polyimide for liquid crystal alignment under non-polarized UV ageing lamp irradiation and a study on the possible mechanism of alignment>, Recommanded Product: (E)-Cinnamoyl chloride, the main research area is photosensitive polyimide liquid crystal UV lamp irradiation alignment.
A new photosensitive polyimide (PI) was successfully synthesized via esterification of PI containing hydroxyl groups with cinnamoyl chloride (CL). The cinnamate (CA) group contents of the PI was up to 90%. The PI films could induce uniform parallel alignment of liquid crystal (LC) mols. after the non-polarized UV ageing lamp exposure, which reduce the cost significantly compared with polarized UV light equipment. In addition, the PI exhibited good thermal stability. Meanwhile, the possible mechanism of PI alignment films induced by NPUVL was discussed in some detail.
Liquid Crystals published new progress about Light-sensitive materials. 17082-09-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C9H7ClO, Recommanded Product: (E)-Cinnamoyl chloride.
