多边形[2 + 2]-和[3 + 3]-型金属配合物是通过双角蛋白二聚体通过锐角间隔子连接而制备的。导电性在很大程度上取决于化合物的堆积排列,揭示了沿[3 + 3]型金属排列轴的相对高迁移率的孔(高达0.11 cm 2 V -1 s -1)存在有效的跳跃路径。桥接程序集。这些观察结果与环状结构中π共轭金属络合物的几何控制有关,这使得它们在装配体中有序排列。

Small‐anglebent‐core liquid‐crystalline (LC) molecules based on a 1,2‐bis(phenylethynyl)benzene central core have been synthesized that form banana smectic phases with a ferroelectric B7–antiferroelectric B2 phase sequence upon cooling. The formation of polar, switchable ferro‐/antiferroelectric bananaphases indicates that, despite the low core bend angle of approximately 60°, banana smectic phases
