  通过CH /π氢键的固态π共轭分子的人字形和螺旋自组装

  摘要：

  通过弱的非共价力（例如CH /π相互作用）以及在固态下形成大的分层超分子结构的创建，有机分子的自组织处于研究的早期阶段。本研究报告了直接证据，表明基于定制设计的低聚亚苯基亚乙烯基（OPV）的π共轭分子中CH /π相互作用驱动的分层自组装，其结构仅尾部的碳原子数不同。这些OPV合子的单晶X射线结构得以解析，并且在晶格中揭示了远距离多臂CH /π相互作用的存在。发现这些π共轭OPV的固态排列对于在晶体中产生右旋人字形堆积或在液晶中间相中产生左旋螺旋至关重要。确定了OPV发色团的螺距和侧倾角位移，以追踪分子倾角对分层结构顺序的影响。此外，在对齐的螺旋结构中对OPV进行了圆二色性研究，以证明分子自组装的存在。因此，本策略为基于弱CH /π氢键的超分子化学开辟了新方法，特别是在π共轭材料中。

  A memory device includes first electrodes, second electrodes, third electrodes, heaters, and memory cells between the first electrodes and the heaters. Each third electrode is provided on the heaters, and each second electrode is provided at a side portion of the heaters. Each memory cell contains an electroconductive liquid crystal compound having a long linear conjugate structure and exhibiting a smectic phase as a liquid crystal phase. Information can be written in the memory cells by selectively heating the heaters to cause the corresponding memory cells to have both electroconductivity and optical anisotropy.
