The poly(ophenylenediamine) molecularly imprinting nanometer layer with high sensitivity to phosphorus agent sarin has been prepared by electropolymerization. Quartz crystal microbalance verifies the existence of molecularly imprinting. Cyclovoltammetry，atomic force microscope and Xray photoelectron spectroscopy have been used to characterize these films. The results show that the layer thickness is only 20 nm，and the film surface is hollowprotruding， lax and has many holes. XPS further certifies that molecularly imprinting mostly influence the threedimension arrangement of polymers， but the chemical composition of polymers does not change. The poly(ophenylenediamine) molecularly imprinting nanometer layers have wide application foreground on the selective detection to the nerve agent sarin.
