Salts of the diazonium coupling agent -phenylenebis(diazonium) form diazonium-terminated conjugated thin films on a variety of conductive and nonconductive surfaces by spontaneous reaction of the coupling agent with the surface. The resulting diazonium-bearing surface can be reacted with various organic and inorganic nucleophiles to form a functionalized surface. These surfaces have been characterized with voltammetry, XPS, infrared and Raman spectroscopy, and atomic force microscopy. Substrates that can be conveniently and quickly modified with this process include ordinary glass, gold, and an intact, fully assembled commercial screen-printed carbon electrode. The scope and convenience of this process make it promising for practical surface modification.
重氮偶联剂——亚苯基双（重氮）的盐通过偶联剂与表面的自发反应，在各种导电和非导电表面上形成重氮端基共轭薄膜。所得的含重氮表面可与各种有机和无机亲核试剂反应，形成功能化表面。这些表面已通过伏安法、X射线光电子能谱、红外和拉曼光谱以及原子力显微镜进行了表征。可以用此方法方便快捷地进行修饰的底物包括普通玻璃、金以及完整的、完全组装好的商用丝网印刷碳电极。该方法的适用范围和便利性使其在实际表面修饰方面具有广阔前景。
