基于二氨基苯基卟啉的新型聚酰亚胺的合成与表征

卟啉类化合物的结构特征使其在很多领域受到广泛的关注,现在通常在卟啉上做修饰以获得更优的性能。以氨基苯基取代的卟啉化合物作为二胺单体和均苯四甲酸二酐为二酐单体,以苯甲酸为溶剂,通过反应合成粗产品新型的聚酰亚胺材料,用丙酮和氯仿洗涤得到纯产品,并进一步合成了Zn-卟啉聚酰亚胺。采用傅里叶红外吸收光谱、紫外-可见吸收光谱对产物进行了结构表征,对主要的紫外光谱、红外光谱吸收带进行了经验归属,以及原料与产物的对比分析,初步确定了合成产物的结构。结果表明,聚合产物是以卟啉骨架结构为主要聚合单元的聚酰亚胺类共聚物。

Synthesis and characterization of polyimide based on 5,15-bis(4-amino-phenyl)-10,20-diphenyl porphyrin

Porphyrin compounds were applied in many fields for their structure property,which were modified to obtain more optimum function.Novel polyimide material was synthesized from 5,15-bis(4-amino-phenyl)-10,20-diphenyl porphyrin and pyromellitic acid dianhydride,in which benzoic acid was used as solvent.The product was purified for synthesizing Zn-porphyrin polyimide,which was charactered by UV-Vis spectra and Fourier IR spectra.The results indicated that the polymer was formed by porphyrin,which was mainly used as backbone and polymeric unit.
