This focus review describes several methods for aligning π-electronic systems to achieve various functionalities in both solution and the solid phase. Cyclic oligomers, acting as tethering units, can facilitate precise design of the nanoarchitecture of π-electronic systems. This approach produces three-dimensionally aligned structures of π-electronic systems in diluted solutions, where the intermolecular interactions are partially excluded. In the solid state, charged π-electronic systems exhibit nanoarchitectures based on electrostatic interactions, including the repulsive and attractive forces generated between the identically charged and differently charged species, respectively. These methods for controlling the arrangements of π-electronic systems can produce fascinating molecular systems. The performance of organic optoelectronic materials is strongly affected by the three-dimensional (3D) alignment of π-electronic systems.

基于精确分子设计的 π 电子系统的明确排列

这篇重点综述描述了几种对齐 π 电子系统以在溶液和固相中实现各种功能的方法。环状低聚物作为系链单元,可以促进 π 电子系统纳米结构的精确设计。这种方法在稀释溶液中产生 π 电子系统的三维对齐结构,其中部分排除了分子间相互作用。在固态下,带电的 π 电子系统表现出基于静电相互作用的纳米结构,包括分别在带相同电荷和不同电荷的物质之间产生的排斥力和吸引力。这些控制 π 电子系统排列的方法可以产生迷人的分子系统。有机光电材料的性能受 π 电子系统的三维 (3D) 排列的强烈影响。这篇重点综述描述了几种对齐 π 电子系统以在溶液和固相中实现各种功能的方法。环状低聚物作为系链单元,可以促进 π 电子系统在稀释溶液中的纳米结构的精确设计。在固态下,带电 π 电子系统表现出基于静电相互作用的纳米结构。这些控制 π 电子系统排列的方法可以产生迷人的分子系统。这篇重点综述描述了几种对齐 π 电子系统以在溶液和固相中实现各种功能的方法。环状低聚物作为系链单元,可以促进 π 电子系统在稀释溶液中的纳米结构的精确设计。在固态下,带电 π 电子系统表现出基于静电相互作用的纳米结构。这些控制 π 电子系统排列的方法可以产生迷人的分子系统。这篇重点综述描述了几种对齐 π 电子系统以在溶液和固相中实现各种功能的方法。环状低聚物作为系链单元,可以促进 π 电子系统在稀释溶液中的纳米结构的精确设计。在固态下,带电 π 电子系统表现出基于静电相互作用的纳米结构。这些控制 π 电子系统排列的方法可以产生迷人的分子系统。
