The present invention relates to photo-crosslinkable liquid crystal monomers with optical activity. The liquid crystal monomers contains one chiral center with an acrylate group or terminal diacrylate groups, and terminal dibenzene rings are introduced in order to extend its hard segment for the purpose of getting a wider liquid crystalline phase. By introducing the liquid crystal monomers, the room temperature nematic liquid crystal or the cholesteric liquid crystal may have a better mutual solubility and a wider, steadier structure of liquid crystal. The liquid crystal monomers have the following formula structure:
本发明涉及具有光学活性的光交联液晶单体。液晶单体包含一个手性中心,带有丙烯酸酯基团或末端二丙烯酸酯基团,并引入末端二苯环,以延伸其硬段,以获得更广的液晶相。通过引入液晶单体,室温向列型液晶或胆甾型液晶可能具有更好的相互溶解性和更广泛、更稳定的液晶结构。液晶单体具有以下结构式:
