SELF-ASSEMBLY POLYMER HAVING HOLE TRANSPORT FUNCTIONAL USED TO ORGANIC PHOTOREFRACTIVE MATERIAL AND PHOTOREFRACTIVE MIXTURE CONTAINING THE POLYMER

摘要

PURPOSE: A self-assembly polymer having a hole transport function used to an organic photorefractive material and a photorefractive mixture containing the polymer are provided, to obtain the self-assembly polymer showing an excellent processability, a rapid responsibility a high optical conductivity based on a high heat stability and a low glass transition temperature and the photorefractive mixture having an excellent stability, a high photorefractivity and no phase separation. CONSTITUTION: The self-assembly polymer comprises the repeating unit represented by the formula 1, wherein A is a hole transport functional group and is represented by the formula 2 or 3; r is an integer of 3-300; X is -C(=O)-O-, -O-C(=O)-, -NH-CO- or -CO-NH-; and M is a co-unit. In the formula 2, R1 is -O-(CH2)q- (wherein q is an integer of 1-20), -S-(CH2)m- (wherein m is an integer of 1-20), -O-(CH2C(CH3)H2)n- (wherein n is an integer of 1-5) or -O-(Si(CH3)2)p- (wherein p is an integer of 1-5). In the formula 2, R2 is -O-(CH2)v-O- (wherein v is an integer of 1-20), -S-(CH2)w-S- (wherein w is an integer of 1-20), -O-(CH2C(CH3)H2)n-O- (wherein n is an integer of 1-5) or -O-(Si(CH3)2)p-O- (wherein p is an integer of 1-5). Preferably, the polymer has a number average molecular weight of 2,000-240,000.
