| 英文摘要 | The surface of a quartz or glass wafer (SiO2/Si(100)) was treated with different aminosilane in solution. The aminosilane layer was allowed to react with aromatic aldehyde to form an imine, the imine was hydrolyzed in a known volume of water to produce the aromatic aldehyde, and subsequently its absorbance was measured by ultraviolet-visible spectroscopy. Thus the observed number of the aldehyde molecules was equivalent to the number of the imine molecules on the surface. With the known surface area of the, substrates and the volume of water, the absolute surface density of the imine, that is, the reactive amine groups on the surface, was calculated. The 9-anthracecarboxaldehyde with high molar extinction coefficient (262 nm, 6.36 X 10(7) cm(2)/mol, 0.8% CH3COOH aq) greatly improved the amino detection limitation of the wafers. By this method the optimal veaction conditions and the stability of the aminosilane laye were studied. The aminosilylated substrates was more stable in the deionized water than in the CH3COOH (0. 8%) aq and KOH (5%) aq. |
