The synthesis and characterization of compounds derived from 9,9-dialkylfluorene and 1,4-dioxane[3,4-b]thiophene are described.
The key step involves a modified Steglich reaction between 9,9-dialkyl-2,7-N,N′-diallyliminochlorofluorene or
2,5-N,N′-diallyliminochloroethylenedioxythiophene and tert-BuOK (Route 1). Route 2 for bis(pyrrol-2-yl)dioxanethiophene,
involving the reaction between 1,4-dioxane[2,3-c]thiophene and a dioxolanepropanol, is also a useful and general strategy.
Molecular modeling studies indicate relationships between the molecular parameters (structure, ionization potential, atomic charges)
of the synthesized moieties and their polymerization properties.
描述了从9,9-二烷基芴和1,4-二氧杂[3,4-b]噻吩衍生的化合物的合成与表征。关键步骤涉及9,9-二烷基-2,7-N,N′-二烯基亚氯芴或2,5-N,N′-二烯基亚氯乙烯二氧噻吩与叔丁基氢氧化钾之间的改进Steglich反应(路线1)。路线2针对双(吡咯-2-基)二氧杂噻吩,涉及1,4-二氧杂[2,3-c]噻吩与二氧杂环丙醇的反应,也是一种有效且通用的策略。分子模拟研究表明,合成部分的分子参数(结构、离子化势、原子电荷)与其聚合特性之间存在关系。
