Research on Performance Influence Factors of Supramolecular Liquid Crystalline Based on Weak Intermolecular Force(Ⅱ)

超分子液晶是利用氢键、离子相互作用;电荷转移相互作用;疏水相互作用及范德华力等弱分子间相互作用构筑的多种超分子液晶复合体系。这种弱分子间力具有动态可逆性,对外部环境(压力、温度、磁场、电场、pH值、光感、化学反应等)具有通过氢键的缔合与解缔合以及电荷转移来改变其结构的独特的响应刺激的功能特性。另外,利用弱分子间力构筑的超分子液晶复合体系具有质量或电荷传输性、传递性、信息储存功能、分子传感等动态功能性、环境友好性及低能耗加工性等特点,故该领域将是未来材料科学体系发展的主方向。对超分子液晶性能影响因素进行了深入分析与研究,并对超分子液晶分类作了介绍。

Supramolecular liquid crystalline is a multi-supramolecular liquid crystallines composite system,and it is constructed by weak intermolecular interaction including hydrogen bond,ion interaction,charge transfer interaction,hydrophobic interaction and van der Waals force and so on.Because the weak intermolecular interaction has dynamic reversibility,the supramolecular liquid crystalline can change structure through association and disassociation of hydrogen bond and charge transfer depending on external environment（pressure,temperature,magnetic field,electric field,pH value,light perception as well as chemical reaction,etc）.Furthermore,the supramolecular liquid crystallines composite system posses dynamic properties such as mass or charge transfer,information storage,molecular sensing,and environmental friendly character and low energy processing performance,so it will be the main development direction of materials science in future.This paper analyzes the performance influence factors in a deep-going way and introduces the classification of supramolecular liquid crystalline.
