简要介绍了盘状液晶的基本概念、分子结构和相态,综述了盘状液晶的分子结构对相的影响、自组装性能、电导性能、光学性能、磁学和铁电性能方面的最新研究进展.盘状液晶柱状相拥有高的有序性和电荷传输速率,作为新型有机半导体材料具有广阔的应用前景.最后,系统概述了盘状液晶材料的应用,并指出了盘状液晶在应用方面存在的问题以及解决问题的方法和建议.

The basic notion of discotic liquid crystal is introduced. In this paper, the structure of molecular and phase, self assemble, carrier transport, optical, magnetic and ferroeletric are reviewed. Discotic columnar mesophases possess high ordering and fast charge mobility, therefore they have wide potential applications as novel organic semi-the application are pointed out and the possible solutions and recommendations are proposed.
