Perfluoroterphenyl, an organic n-semiconductor, has been derivatized by short ω-mercaptoalkyl chains to permit the formation of self-assembled monolayers on semiconductor and coinage metal substrates. Because the perfluoroaryl rings are prone to nucleophilic attack, strategies for the introduction of the side chains had to be developed that avoid the use of any nucleophiles. Keeping this in mind, the
全氟三联苯是一种有机 n-半导体,已通过短 ω-巯基烷基链衍生化,以允许在半导体和造币金属基材上形成自组装单层。由于全氟芳基环容易受到亲核攻击,因此必须开发引入侧链的策略,以避免使用任何亲核试剂。牢记这一点,可以以良好的收率获得在烷基接头中具有一个、两个和三个亚甲基的相应衍生物。其中一种中间体(全氟三联苯-4-基)甲醇的晶体结构表现出分子的平行排列以及全氟三联苯部分的螺旋结构,这与大多数非氟化三联苯衍生物的结构形成对比。以Au(111)为测试底物,
