Based on trityl moieties, novel organic building blocks have been prepared and structurally investigated. Substituted hexaphenyl-p-xylene (1,4-ditritylbenzene) as well as extended analogues thereof were prepared. Furthermore, a new family based on a 1,3,5-tritritylbenzene motif, connecting three trityl groups through a formal mesitylene unit, was developed. Both families were further converted through
基于三苯甲基部分,新的有机结构单元已被制备和结构研究。制备了取代的六苯基-对二甲苯(1,4-二三苯甲基苯)及其扩展的类似物。此外,开发了一个基于 1,3,5-三苯甲基苯基序的新家族,通过正式的均三甲苯单元连接三个三苯甲基。这两个家族分别通过六倍和九倍取代反应进一步转化,以产生用于超分子组装的有效分子构建块。
