含偶氮苯聚芳亚胺的合成、表征和光谱分析

摘要

With 4,4′-dibromobenzophenone and 4,4′-diaminoazobenzene as monomers, poly(arylimine) containing azobenzene unite (PAI-A) was synthesized via palladium-catalyzed amination. The structure of PAI-A was characterized by means of FT-IR, 1H NMR and elemental analysis, the result shows an agreement with the proposed structure. The UV absorption apectra were tested under different conditions.%以4,4′-二溴二苯甲酮和4,4′-二氨基偶氮苯为单体,通过钯催化的胺基化反应缩聚合成了含偶氮苯基团的新型结构聚芳亚胺(PAI-A).PAI-A结构通过FT-IR, 1H NMR和元素分析测定,测试结果和目标产物吻合良好.在不同的条件下测定了聚合物的光学性能.
