[Abstract]:Salicylaldehyde arylamine Shiff base TPE-SA1,TPE-SA2,TPE-SA3,TPE-SA4,TPE-SA5. based on tetrastyrene group was synthesized by carbon and nitrogen double bond connection between tetrastyrene group and substituted salicylaldehyde. The molecular structure of the compounds was characterized by IR,NMR,MS and elemental analysis. The optical, electrochemical and thermal stability properties of the compounds were investigated by UV-vis spectra, molecular fluorescence spectra, cyclic Voltammetric analysis and thermogravimetric measurements. The experimental results show that the UV absorption peaks of B band and R band appear in the pure THF solution at 260 nm and 370 nm, respectively, and show typical aggregation induced luminous (AIE) properties in the mixed solution of tetrahydrofuran / water. The thermal decomposition temperature of the target compound is 262283295278299 鈩，
