A polymer containing triazine rings that has a molecular weight of 5,000 - 1,000,000 and that comprises a recurring unit represented by the general formula (I):
wherein X1 and X2 are each independently S, NR1 (R is a hydrogen atom, an alkyl group or an aryl group) or O; Y may be an alkylene group, a divalent substituted or unsubstituted aromatic ring group that do not contain chromophore moieties or a group in which said aromatic ring groups are bonded or condensed together; Z is either a spacer group comprising a group represented by -G-(CH2)n- (n is an integer of 1 - 10) or a direct bond (G is S, NR4 or O, and R4 is a hydrogen atom, an alkyl group or an aryl group); and A is an organic chromophore moiety in which an electron donative group and an electron attractive group are conjugated via a π-electron system. The polymer is lightproof, forms a thin film of high quality and has a high glass transition point.
一种含有三嗪环的聚合物,分子量在 5,000-1,000,000 之间,由通式(I)代表的循环单元组成:
其中 X1 和 X2 各自独立地为 S、NR1(R 为氢原子、烷基或芳基)或 O;Y 可以是亚烷基、不含发色团分子的二价取代或未取代的芳环基团或上述芳环基团键合或缩合在一起的基团;Z 是由 -G-(CH2)n-(n 是 1-10 的整数)代表的基团或直接键(G 是 S、NR4 或 O,R4 是氢原子、烷基或芳基)组成的间隔基团;以及 A 是有机发色团分子,其中电子捐赠基团和电子吸引基团通过 π 电子系统共轭。这种聚合物耐光,能形成高质量的薄膜,并具有较高的玻璃化转变点。
