摘　　要：香豆素材料由于具有荧光和光二聚作用,以及荧光量子产率高、Stokes位移大、光物理和光化学性质可调以及光稳定性好等优点,被应用于许多领域,如荧光材料、激光染料、光折射材料、非线性光学材料、采光材料以及液晶取向层材料等.香豆素类作为一种光敏性基团已被引入到液晶分子中,使液晶分子不仅具有自组装性质,同时具有优异的光电性质.该文综述了近年来含有香豆素光敏基团的液晶化合物的研究进展.Because of their fluorescence and photodimerization properties, as well as their high fluorescence quantum yields, high molar extinction coefficient, easy chemical modification and good photostability, coumarin derivatives are very useful in many fields such as fluorescent materials and laser dyes, photo-refractive materials, nonlinear optical materials, light harvesting materials, alignment layers for liquid crystals, ect. Liquid crystals containing coumarin unit have been designed, the obtained coumarin-based liquid crystals have not only self assembled properties but also excellent electrooptical properties.In this paper the progress on coumarin-based liquid crystals have been reviewed, including the structure characteristics, liquid crystalline properties and potential applications.
