摘　　要：通过紫外-可见光谱跟踪研究了四磺酸基酞菁钆/重氮树脂DAR/GdTs2薄膜的自组装过程，利用原子力显微镜（AFM）表征了自组装薄膜的形貌，制备了（DAR/GdTs（Pc）2）修饰玻碳电极，应用循环伏安法测试了（DAR/GdTs（Pc）2）修饰玻碳电极对抗坏血酸的电催化性能，表明在1～9 mmol/L范围内峰电流与抗坏血酸的浓度有较好的线性关系。Glassy carbon electrodes modified with alternating multilayer films containing gadolinium tetrasulfophthalocyanine （ GdTs（ Pc ） 2 ） and diazo -resins （ DAR ） were fabricated by the electrostatic self -assembly （ESA） technique.The ultraviolet-uisible spectrophotometer （UV-Vis） analysis results indicated that the DAR/GdTs （ Pc） 2 self -assembled multilayer films were successfully fabricated , interface were studied by the Atomic Force Microscope（AFM）.The electrocatalytic oxidation of ascorbic acid （AA） on the modified electrode was investigated by cyclic voltammetry technique , and it was found that the modified electrode exhibited good sensitivity for catalytic oxidation of ascorbic acid （ AA）.It showed the linear relationship between peak current and the concentrations of ascorbic acid （ AA） over the range 1~9 mmol/L.
