英文摘要	应用循环伏安法、微分脉冲伏安法、紫外-可见和荧光光谱研究了一种新型钌化卟啉[Ru(phen)2(MPyTMPP)Cl]+(phen=1,10-邻菲咯啉,MPyTMPP=5-(3-吡啶)-10,15,20-三-(4-甲苯基)-卟啉)在多壁碳纳米管(MWCNTs)修饰的玻碳(GC)电极表面的电化学特性及其与电极上和溶液中双十六烷基磷酸盐(DHP)的作用.结果表明:[Ru(phen)2(MPyTMPP)Cl]+能强吸附在MWCNTs-DHP/GC电极表面,并呈现一对由表面过程控制的氧化还原峰;适量DHP有利于该配合物的吸附固定;[Ru(phen)2(MPyTMPP)Cl]+能与溶液中的DHP形成结合体,导致配合物中心离子反应电位负移.; Electrochemical properties of a novel monoruthenated porphyrin [Ru(phen)2(MPyTMPP)Cl]+ (where phen =1,10-phenanthroline,MPyTMPP =5-(3-pyridyl)-10,15,20-tris-(4-methylphenyl) porphyrin) on a multi-walled carbon nanotubes (MWCNTs) modified glassy carbon (GC) electrode with the participation of dihexadecyl phosphate (DHP) have been investigated by using cyclic voltammetry,differential pulse voltammetry,UV-Visible spectroscopy and fluorescence spectroscopy. It is found that [Ru(phen)2(MPyTMPP)Cl]+ has the ability to adsorb strongly onto the MWCNTs-DHP modified GC electrode and exhibits a pair of redox waves controlled by surface electrochemical process. DHP dispersed on the MWCNTs/GC electrode can facilitate the ruthenium complex to adsorb onto the MWCNTs-DHP surface. A new complex is generated by the interaction of [Ru(phen)2(MPyTMPP)Cl]+ on the modified electrode with DHP in buffer solution and its formal potential corresponding to the Ru(III)/Ru(II) reaction indicates an negative shift.; 作者联系地址：华南师范大学化学与环境学院;广东药学院药科学院;; Author's Address: 1.
