                 摘要:介绍了四苯基乙烯类、二苯基丙烯腈类、二苯基乙炔类、聚集诱导发光分子修饰的苯并菲类以及其他的
                 具有聚集诱导发光性质的液晶材料,重点阐述了它们的聚集诱导发光性质和液晶自组装性质,并说明了各自的
                 构效关系。综合文献报道可知:将发光液晶材料应用在光电器件上能极大地节约成本和减少能耗。最后指出,
                 在合成该类发光液晶材料时,需合理地利用聚集诱导发光基团和液晶基团,且研究重点应集中在此类材料发光
                 机理的研究和应用范围的拓展上。

                 Abstract: Tetraphenylethene, diphenylacrylonitrile, diphenylacetylene, triphenylene decorated with aggregation-
                 induced  emission  (AIE)  and  other  liquid  crystal  materials  are  introduced.  Their  AIE  and  liquid  crystal
                 properties  are  mainly  described  and  their  structure-activity  relationship  is  also  illustrated.  Literatures
                 reported show the use of light-emitting liquid crystal materials in optoelectronic devices can greatly reduce
                 costs and energy consumption. Finally, it is pointed out that in the synthesis of such luminescent liquid
                 crystal materials, it is necessary to reasonably utilize AIE and liquid crystal groups and the future study
                 should focus on the luminous mechanism of such materials and their extension of the application range.
