合成了5-(4-羟基苯基)-10,15,20-三苯基卟啉锌配合物,与活化的多壁碳纳米管(MWNT)发生酯化反应,从而得到金属卟啉有机共价化学修饰的多壁碳纳米管复合物;利用金属卟啉环上的π电子与多壁碳纳米管管壁上的π电子通过π-π堆积效应,得到金属卟啉有机非共价修饰的多壁碳纳米管复合物.通过透射电镜(TEM)考察了金属卟啉-多壁碳纳米管复合物的形貌特征;通过红外光谱对产物的化学结构进行了表征;通过紫外光谱、荧光光谱和热失重分析(TGA)对比分析了两类复合物,发现非共价修饰的金属卟啉-碳纳米管复合物的荧光淬灭率更高,非共价修饰的金属卟啉-碳纳米管复合物中卟啉的含量比较高.
Synthesis of zinc 5- (4-hydroxyphenyl) -10,15,20-triphenylporphyrin complexes and activated multi-walled carbon nanotubes (MWNT) esterification reaction to obtain a total of porphyrin organics Valence-chemical modified multi-walled carbon nanotube composite; the π-electron on the metal porphyrin ring and the π-electron on the wall of the multi-walled carbon nanotube pass the π-π stacking effect to obtain the organic noncovalent modification of the metal porphyrin The morphology of the metalloporphyrin-MWCNTs was characterized by transmission electron microscopy (TEM). The chemical structure of the product was characterized by infrared spectroscopy. The UV-Vis spectra, fluorescence spectra Compared with TGA, it was found that the fluorescence quenching rate of non-covalently modified metalloporphyrin-CNTs was higher than that of non-covalently modified metalloporphyrin-CNTs Complex porphyrin content is relatively high.
