Abstract

A series of electron-accepting azaacene-type materials - with different kinds and degrees of intermolecular interactions were synthesized. Simple modification of the terminal substituents significantly modulated the photophysical and electrochemical properties. The degree of weak intermolecular interaction determined the emergence of a liquid crystalline (LC) phase for each compound. Dipole-dipole interaction, π-π interaction, and van der Waals interaction all contributed to stabilize the LC phase of and . The introduction of strong hydrogen bonding interaction enabled the formation of a highly ordered LC phase in . Charge-transport properties of , , and were also investigated.

摘要

合成了一系列具有不同种类和程度分子间相互作用的电子接受型氮杂并苯类材料。末端取代基的简单修饰显著调节了光物理和电化学性质。弱分子间相互作用的程度决定了每种化合物液晶（LC）相的出现。偶极-偶极相互作用、π-π相互作用和范德华相互作用都有助于稳定[具体化合物1]和[具体化合物2]的LC相。强氢键相互作用的引入使得[具体化合物3]中形成了高度有序的LC相。还研究了[具体化合物1]、[具体化合物2]和[具体化合物3]的电荷传输性质。
