Description

[0001] 【Technical field】 [0002] The invention relates to the field of fluorescent materials, in particular to an axial chiral compound with aggregation-induced luminescent properties and a preparation method and application thereof. [0003] 【Background technique】 [0004] Compared with traditional inorganic semiconductor materials, new organic light-emitting semiconductor functional materials used in solid state or aggregated state have the advantages of high sensitivity, good device flexibility, low cost, small device size, large area preparation and easy integration. The field of optoelectronic research has received more and more attention (Chem. Phys. Lett., 1974, 29, 277, Chem. Rev. 2007, 107, 1011). In addition to organic optoelectronic devices, organic light-emitting materials are used in information storage (J.Mater.Chem.C,2013,1,3376; Chem.Soc.Rev.,2013,42,857; Adv.Mater.,2013,25,378; Chem.Soc. Rev., 2013, 42, 8895.) and biological sciences (Chem. Rev., 2013, 113, 1...
