A perylene bisimide derivative bearing two phenyl substituents with chiral solubilizing alkyl chains at the imide N atoms has been synthesized, and its self-assembly properties in solution and condensed phase have been investigated. Temperature-dependent CD spectra revealed the coexistence of two different kinds of chiral aggregates, differing in size and handedness. The chiral side chains effect a higher order within the self-assemblies, resulting in an increased charge-carrier mobility in the columnar liquid crystalline mesophase. [structure: see text]
合成了一种在酰亚胺 N 原子上带有两个苯基取代基且带有手性增溶烷基链的苝二酰亚胺衍生物，并研究了其在溶液和凝聚相中的自组装性质。温度依赖性圆二色光谱揭示了两种不同类型手性聚集体的共存，它们在尺寸和手性方面存在差异。手性侧链在自组装中产生更高的有序性，导致柱状液晶中间相中电荷载流子迁移率增加。[结构：见正文]
