【摘要】：将四苯乙烯基与取代水杨醛通过碳氮双键连接起来,合成了基于四苯乙烯基的水杨醛缩芳胺希夫碱TPE-SA1、TPE-SA2、TPE-SA3、TPE-SA4、TPE-SA5。利用IR、NMR、MS和元素分析等对其分子结构进行表征,通过紫外-可见光谱、分子荧光光谱、循环伏安分析法和热重测试分别考察了该类化合物的光学、电化学和热稳定性质。实验结果表明:该类化合物在纯THF溶液中,分别在260 nm和370 nm左右处出现B带和R带紫外吸收峰;在四氢呋喃/水的混合溶液中,表现出典型的聚集诱导发光(AIE)性能。目标化合物的热分解温度分别为262,283,295,278,299℃,具有较好的热稳定性。它们的电离势分别为5.31,5.43,5.41,5.30,5.15eV,电子亲合势均大于4.3 eV。
[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，
