通过氢封端的硅表面与乙烯基邻苯二甲酰亚胺的反应，在硅（111）上制备了邻苯二甲酰亚胺单分子层。在甲胺溶液中进行邻苯二甲酰亚胺在硅表面的水解反应以制备氨基封端的单分子层。用衰减全反射红外光谱和原子力显微镜研究了制备氨基封端单层的一系列反应。这项工作提供了一种简单的方法来制备氨基封端的有机单层作为锚定层来固定染料、DNA 和蛋白质等功能分子。 (C) 2007 Elsevier B.V. 保留所有权利。
Phthalimide monolayers were prepared on silicon (111) by the reaction of hydrogen-terminated silicon surfaces with vinylphthalimide. The hydrolysis reaction of phthalimide on silicon surfaces was performed in a methylamine solution to prepare amino-terminated monolayers. A series of reactions to prepare amino-terminated monolayers was investigated with attenuated total reflectance infrared spectroscopy and atomic force microscopy. This work provides a simple method to prepare amino-terminated organic monolayers act as anchor layers to immobilize functional molecules such as dyes, DNA and proteins. (C) 2007 Elsevier B.V.
