A series of 4-alkyl-1-bromosulfanylbenzenes having S-methyl 2, S-t-butyl 3, S-trityl 4, S-benzyl 5, and S-silylethoxymethyl 6 substituents were prepared and evaluated for their ability to form a monolayer consisting of an S-aryl adsorbate on Au (111) surface. The monolayer was formed via the selective hydrolytic removal of an alkyl group protecting the sulfur functionality upon adsorbtion onto the gold surface. Thiols having variable carbon chain length and a peripheral thiophene moiety 9, 10, 17, 18 and 23-26 were also prepared.
制备了一系列4-烷基-1-溴硫代苯,包括S-甲基2、S-叔丁基3、S-三苯甲基4、S-苄基5和S-硅乙氧甲基6取代基,并评估它们在金(111)表面形成由S-芳基吸附物组成的单层膜的能力。单层膜的形成是通过在吸附到金表面时选择性地水解去除保护硫官能团的烷基。还制备了具有可变碳链长度和外围噻吩基团的硫醇9, 10, 17, 18和23-26。
