一种新型共轭Schiff碱聚合物的合成与表征

摘要

以对苯二甲醛和水合肼为原料,无水乙醇作溶剂合成了一种共轭Schiff碱聚合物,并通过GPC、IR、1H NMR、紫外-可见吸收光谱和荧光光谱对其分子量和组成结构进行表征.结果表明,该物质为一种分子量较大的共轭Schiff碱聚合物,具有良好的荧光性.%A novel of conjugated Schiff base polymer was synthesized under the condition that 1,4-phthaI-aldehyde and 80% hydrazine hydrate were used as raw materials, and the ethanol as solvent. Its molecular weight and composition of structure were characterized by GPC.IR.1H NMR.UV-visible absorption spectra and fluorescence spectra. The results indicated that this matter is a conjugate Schiff base polymer with greater molecular weight and has strong fluorescence.
