盘状液晶分子具有平面盘状结构且能在一定条件下排列成有序的柱状相,其特有的柱状相结构使得这类材料具有特殊的性质,在光电转换、有机半导体及液晶磁性材料等方面有着广泛的应用,因此受到广大科研工作者越来越多的关注。本文主要综述了近十几年来国内外文献报道的含炔基的盘状液晶分子及其性质,着重讨论炔基基团在不同的位置时对盘状液晶性能的影响。
The discotic liquid crystal molecules have a planar discoid structure and can be arranged in an orderly columnar phase under certain conditions. Their unique columnar phase structures make these materials have special properties. In the fields of photoelectric conversion, organic semiconductors and liquid crystal magnetic materials Has a wide range of applications, so by the majority of researchers more and more attention. This review summarizes the properties and properties of alkynyl-containing discotic liquid crystal molecules reported in domestic and foreign literature over the past decade and focuses on the influence of alkynyl groups on the discotic liquid crystal properties at different positions.
