摘　　要：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。Discotic liquid crystal molecules generally have a planar discotic structure and can self-organize to form ordered columnar phase,which makes these molecules have special properties and a wide range of applications in the photoelectric conversion,organic semiconductors and liquid crystal magnetic materials.Therefore,these materials attract more and more attention.In this paper,the structures and properties of discotic liquid crystal molecules with alkynyl side chains reported in domestic and foreign literatures in the past ten years were summarized,especially focusing on the effects of the alkynyl groups in different positions on the properties of the discotic liquid crystal molecules.
