Abstract

Abstract:

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.

Key words: discoid liquid crystal, columnar phase, alkynyl, dimer, liquid crystal polymer
