Abstract: 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 run, 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
