摘要
The wholly aromatic polyester copolymer represented by the general formula (I) provided in the present invention exhibits excellent nonlinear optical properties.;In general formula (I), R 1 is a halogen group element, OH, or OR (R is a C1-C5 alkyl group).;R 2 is -O- (CH 2 ) l -O- (l is an integer from 1 to 20), -S- (CH 2 ) m -S- (m is an integer from 1 to 20), (n is an integer from 1 to 5, Y is CH 3 ) or (p is an integer from 1 to 6), R 3 is NO 2 , CN, And R is an alkyl group having 1 to 6 carbon atoms.
