Paragraph 0059; 0061; 0062; 0063, (2017/09/05)
The invention discloses a hybrid tetra-aryl ethylene compound. The structure of the hybrid tetra-aryl ethylene compound is as shown in the specification, wherein, Ar1 is phenyl or hexahydric heteroaryl; Ar2 and Ar3 are phenyl, hexahydric heteroaryl or quinary heteroaryl independently and respectively; X is nitrogen, oxygen, sulphur or silicon; R1, R2 and R3 are hydrogen, fluorine, chorine, bromine, iodine, methyl, ethyl, propyl, isopropyl, normal-butyl, isobutyl, tertiary butyl, methoxy, ethyoxyl, amino, hydroxyl, carboxyl, nitryl, sulfonic acid group, trifluoromethyl, phenyl, benzyl, benzoyl, para-bromophenyl, para-fluorophenyl, thiophene, pyridine, or crown ether. The invention further discloses a preparation method of the hybrid tetra-aryl ethylene compound and an application thereof, and discloses a polymer of the hybrid tetra-aryl ethylene compound, a preparation method and an application thereof. The hybrid tetra-aryl ethylene compound is unique in structure performance; the compound has good photochromic performance as well as excellent aggregation-induced emission performance.
