摘　　要：采用新方法合成了meso-四(4-酰肼基苯基)卟啉及其金属配合物,通过化学键将酰肼卟啉上的酰肼基与活化的多壁碳纳米管(MWNTs)发生酰胺化反应,从而得到卟啉共价化学修饰的多壁碳纳米管复合物;利用卟啉环上的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,得到卟啉非共价化学修饰的碳纳米管复合物.通过红外光谱、紫外和荧光光谱对比分析,发现在卟啉与碳纳米管间存在强烈的电子效应,且非共价修饰的卟啉-碳纳米管复合物的荧光猝灭率更高.Tetra-（4-hydrazidephenyl） porphyrin and its Cu,Zn complexes were synthesized with new techniques.The covalent porphyrins-functionalized MWNTs were gained by amidation reaction between the oxidized multi-walled carbon nanotubes（MWNTs） and the hydrazide porphyrins.The non-covalent porphyrinsfunctionalized MWNTs were obtained throughπ-πpileup with tetra-（4-hydrazidephenyl） porphyrin and MWNTs.The structures of the resultant products were characterized by FTIR.Strong electronic effects between porphyrins and MWNTs were found from UV-Vis absorption and fluorescence spectroscopy.Moreover,non-covalent composites provide a higher emission quenching compared with covalent composites.
