摘　　要：合成了meso-四(4-磺酸钠苯基)卟啉及其Zn,Cu,Mn配合物,通过共价与非共价的方法将其分别修饰到多壁碳纳米管上.采用红外光谱对产物结构进行表征;通过透射电镜(TEM)考察了卟啉-多壁碳纳米管复合物的形貌特征;通过紫外光谱、荧光光谱对比分析了两类复合物,发现在卟啉与多壁碳纳米管之间存在较强的电子效应,同时发现非共价修饰的卟啉-碳纳米管复合物的荧光淬灭率更高;热重分析(TGA)表明非共价的卟啉-碳纳米管复合物中卟啉的含量比较高.对修饰后的复合物进行了溶解性测试,结果表明共价修饰的复合物在水中有较好的溶解性和分散性.meso-Tetra（4-sulfonate sodium phenyl）porphyrin and its Zn, Cu, Mn complexes were synthesized. Porphyrins-MWNTs compounds were obtained by covalently and noncovalently methods. The structures of the resultant products were characterized by FTIR and the morphology features were investigated by transmission electron microscopy （TEM）. Strong electeonic effects between porphyrins and MWNTs were found from UV-vis absorption and fluorescence spectroscopy, moreover, the noncovolant functionalization provides a higher fluourescence quenching than the covalent functionalization. The thermal gravity analysis （TGA） showed that the weight percentage of the porphyrins and its metal complexes attached to MWNTs which the noncovolant functionalization is more than convalent functionalization. The solubility of new compounds was tested, and the results show that the covalently modified complexes have good solubility and dispersion.
