主链含均三嗪环D-π-A型共轭聚合物的合成及发光性能

Synthesis and luminescence properties of D-π-A type conjugate polymer in main chain

用乙腈和无水乙醇合成了三甲基均三嗪,然后依次与正丁醛、对苯二甲醛缩合反应,首次制备了主链含均三嗪环D-π-A型共轭聚合物;用红外光谱、紫外光谱和氢谱对共轭聚合物进行了表征,确定是所需要的目标聚合物。该聚合物在360 nm紫外光的激发下,发出597 nm较强的纯正红光,是一种潜在的白光聚合物电致发光器件所需要的红光材料。

Trimethyl-s-triazine was synthesized with acetonitrile and absolute ethyl alcohol firstly and D-π-A type conjugate polymer(P)containing s-triazine was prepared by condensation reaction with butyraldehyde and phthalaldehyde successively.The conjugate polymer was characterized by IR,UV and 1H NMR and confirmed target polymer.The conjugate polymer emitted pure stronger red light at 597 nm when excited by 360 nm UV light.It is potential red material of WPLED(white polymer light emitting diode).
