dithiol 4T 15 with two TMSE‐protected thiolate groups have been immobilized on a gold surface as monolayers that have been characterized by CV, ellipsometry, contact‐angle measurement, and X‐ray photoelectron spectroscopy (XPS). The results show that molecules 14 and 15 are doubly grafted with a horizontal orientation of the conjugated system relative to the surface. Furthermore, application of the d
描述了一系列带有2-氰基乙基(CNE),2-三甲基甲硅烷基乙基(TMSE)和乙酰基(Ac)保护的硫醇盐基团的四噻吩(4T)的合成和表征。这些不同的保护基的顺序切割允许制备用二茂铁和/或烷硫醇链衍生的4T。这些化合物的电化学行为已通过循环伏安法(CV)在溶液中进行了分析。二茂铁衍生的二硫醇4T 14和具有两个TMSE保护的硫醇盐基团的二硫醇4T 15已被固定在金表面上,作为单层,已通过CV,椭偏,接触角测量和X射线光电子能谱(XPS)进行了表征)。结果表明,分子14和以共轭体系相对于表面的水平取向将图15所示的结构双重嫁接。此外,在15个单层上应用其余保护的硫醇盐基团的脱保护/烷基化顺序可实现有效的后功能化。
