两种三苯胺氰基取代二苯乙烯类席夫碱衍生物的合成及性质

Synthesis and Properties of Two Kinds of Schiff-base Derivatives of Triphenylamino Cyano Stilbene

以三苯胺、对硝基苯乙腈等为原料,采用亲核取代反应、Vilsmeier甲酰化、Knoevenagel反应等合成了三苯胺基氰基取代二苯乙烯类席夫碱衍生物Y1,Y2。运用质谱、核磁共振谱进行了表征,同时研究了目标分子的聚集诱导发光效应、电化学性质和在六种不同极性溶剂中的紫外可见吸收、荧光发射性质。为寻找新的发光材料进行了有益的探索。

Using triphenylamine and p-nitro benzyl cynide as raw materials,two kinds of Schiff-base derivatives(Y1,Y2)of triphenylamino cyano stilbene were designed and synthesized by way of nucleophilic substitution reaction,Vilsmeier formylation and Knoevenagel reaction.The structure of the products was characterized by 1 H NMR and MS.The aggregation-induced emission(AIE),electrochemical properties and UV-visible and fluorescence emission properties in six solvents with different polarity of the target compounds were tested.The results demonstrated that this work is beneficial for the exploration of new luminescent materials.
