摘要: 巯基羧酸吸附在金电极表面形成自组装单分子层,其中巯基与金共价结合,而裸露在表面的羧基可用于进一步修饰.用逐层反应的方法,可通过乙二胺将二茂铁羧酸结合在自组装单分子层上.电极的行为用电化学方法进行了表征.

关键词: 自组装单分子层, 金电极, 逐层修饰

Abstract: The self-assembled monolayers,which were built by spontaneous adsorption of ω-carboxylic acid thiols on gold surface,were used as substrate for further modification through later bylayer amide surface reactions.At each stage of modification,the gold surface was characterizedelectochemieally. The results demonstrated that the strategies of layer by layer self assembly is ofsignificant potential for fabrieating functionalized ultrathin layers.

Key words: Self.assembled monolayer, Gold electrede, Layer by layer medification
