Abstract
Abstract The photo-alignment with the linear-polarized UV (LP-UV) light was applied to the surface modified polyimide film with chalcone derivatives for the vertical alignment of liquid crystal molecules. The LP-UV light irradiation caused either dimerization or isomerization of chalcone derivatives. The long alkyl-chains attached on the chalcone derivatives were aligned homeotropically and so are LC-molecules.
