摘要： 利用电化学技术及扫描隧道显微镜(STM),于0.1mol/LHClO4溶液中研究了Schiff碱N-aete-N在单晶Au(111)面上所形成的自组装单分子膜(SAMs)的电化学性质及结构.N-aete-N在Au(111)电极表面的吸附抑制了金的阳极氧化,同时使固/液界面双层电容明显降低.观察到N-aete-NSAMs的高分辨STM图像.N-aete-N分子在Au(111)表面上以(6×7)结构单胞呈二维有序排列,其表面浓度为5.5×10-11mol/cm2.

Abstract: The self-assembled monolayer of Schiff base N-aete-Nmolecules on Au(111) in 0.1mol/L HClO4solution has been investigated by electrochemical measurements and in situ STM.Two-dimensional ordered molecular arrays with a (6×7) commensurate structure were observed.The N-aete-Nmolecules are adsorbed on Au(111) in a flat-lying orientation and with a surface concentration of 5.5×10-11mol/cm2.

Key words: Electrochemistry, in situ STM, Au(111), Schiff base, Self-assembled monolayer film
