| titleOfInvention | Photo-functional high molecular azobenzene compound and method for the preparation thereof, and method for preparing high molecular liquid crystal oriented layer using the same |
| abstract | The present invention relates to a photofunctional polymer material and a method for manufacturing the same, and a method for preparing a polymer alignment layer for a liquid crystal display using the same, wherein the reactant obtained by reacting a diaminoazobenzene compound with tetracarboxylic anhydride is purified and dried. Azopolyamic acid of Chemical Formula 1, which is a photofunctional polymer material, is prepared, dissolved in an organic solvent, coated on a substrate, exposed to polarized ultraviolet light, reoriented, and heat treated to azopolyimide of Chemical Formula 2 By producing a polymer alignment film by hydration, it is possible to prepare a polymer alignment film for a liquid crystal display that can adjust the tilt angle in a desired range without causing problems that may be caused by rubbing:n n n n n n n n n n n n n n n n n Wheren n n R is a C 9-18 alkyl group,n n n a is 0.05 to 0.7, b is 0.3 to 0.95, a + b is 1,n n n X isn n n n n n n n Y isn n n n n n n n n is an integer of 2 or more. |
