    • A third-order nonlinear optical main chain polymer material contains a high .chi..sup.(3) component having no less than 3 but no more than 7 .pi.-conjugated bonding groups and having an electron donor in the main chain of the polymer through covalent bonds. The donor is preferably an alkylamino structure, more preferably a dialkylamino structure. Particularly preferred is a diethylamino structure. The high .chi..sup.(3) component is preferably a phenylene ring system of which phenylene rings are bonded through azo bonding groups with the phenylene rings and the azo bonding groups being positioned alternately. The polymer main chain is polyurethane or polyester. The third-order nonlinear optical main chain polymer material is prepared by polyaddition of a high .chi..sup.(3) compound, i.e., a precursor of the high .chi..sup.(3) component, having a hydroxyl group at each end with a diisocyanate compound or by polycondensation of the high .chi..sup.(3) compound with a dicarboxylic acid.
    • 三阶非线性光学主链聚合物材料包含具有不少于3个但不超过7个π共轭键合基团的高岐(3)组分,并且通过共价键在聚合物主链中具有电子给体。 给体优选为烷基氨基结构,更优选为二烷基氨基结构。 特别优选的是二乙基氨基结构。 高岐(3)成分优选为亚苯环系,其中亚苯环通过偶氮键合基与亚苯基环并且偶氮键基交替定位。 聚合物主链是聚氨酯或聚酯。 三阶非线性光学主链聚合物材料通过将高岐(3)化合物,即高岐(3)组分的前体,其末端具有二异氰酸酯化合物的羟基或通过缩聚反应 的高岐(3)化合物与二羧酸。
