合成了5-(4-氨基)苯基-10,15,20-三苯基卟啉及其铜配合物, 通过化学键将氨基卟啉与活化的多壁碳纳米管(MWNT)发生酰胺化反应, 从而得到卟啉有机共价化学修饰的多壁碳纳米管的复合物. 通过红外光谱对产物的化学结构进行了表征, 证实了复合物体系中酰胺反应的发生. 紫外可见光吸收光谱和荧光光谱分析确定了卟啉与多壁碳纳米管间存在强烈的电子效应. 通过透射电镜(TEM)观察了产物的形貌特征, 发现碳纳米管壁上连接上了氨基卟啉小分子, 进一步证实了酰胺化反应的发生.

关键词: 氨基卟啉, 碳纳米管, 共价化学修饰, 复合物

5-(4-Aminophenyl)-10,15,20-triphenylporphyrin and its copper(II) complex were synthesized. Then through the covalently chemical reaction between the oxidized multi-walled carbon nanotubes (MWNT) and the amino porphyrins, the composites were gotten. The chemical properties of the resultant products were characterized by FT-IR, finding the amidation reactions in the composites. Strong intramolecular interaction between the amino porphyrins and MWNT was found from UV-Vis absorption and fluorescence spectroscopy. The morphology of the functionalized MWNT was also observed using transmission electron microscopy, revealing that the amino porphyrins were attached to the sidewalls of MWNT.

Key words: amino porphyrin, carbon nanotube, covalently chemical functionalized, composite
