合成了一系列具有不同种类和程度分子间相互作用的氮杂并苯类电子受体材料1 - 4。末端取代基的简单修饰显著地调节了化合物的物理和电化学性质。弱分子间相互作用的程度决定了每种化合物的液晶（LC）相的出现。偶极-偶极相互作用、π-π相互作用和货车德瓦耳斯相互作用都有助于稳定1和2的LC相。强氢键相互作用的引入使得在4中形成高度有序的LC相。并研究了化合物1、2和4的电荷输运性质。
A series of electron-accepting azaacene-type materials1–4with 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 of1and2. The introduction of strong hydrogen bonding interaction enabled the formation of a highly ordered LC phase in4. Charge-transport properties of1,2, and4were also investigated.
