According to structural data and phase transition behaviors, it was suggested that the positions of the substituents significantly influence molecular alignments in liquid crystals as well as thermal properties. In particular, the columnar structures, which are favorable for expressing efficient carrier transportation, were observed in the 5AP derivative. These results suggest that the 5AP scaffold could
我们描述了由三角形 π 共轭分子、1,3,4,6,9b-五氮杂苯 (5AP) 组成的液晶的合成和相变行为。具有3,4,5-三(

生物Ph)是通过改变取代基位置来制备的。从热和结构分析中,从所有衍
生物中观察到液晶相。根据结构数据和相变行为,表明取代基的位置显着影响液晶中的分子排列以及热性能。特别是,在 5AP 衍
生物中观察到有利于表达有效载流子传输的柱状结构。这些结果表明,5AP 支架可能是通过分子结构的略微不同模式构建各种聚集结构的平台。讨论了这些转变的合理模型。
