摘　　要：以4-二乙氨基水杨醛和对硝基苯乙腈为原料,经Knoevenagel缩合反应和Williamson反应合成了一个新型的D-π-A型氰基取代二苯乙烯衍生物(M1);用Na_2S将M1硝基还原为氨基,合成了一个新型的D-π-A-D型氰基取代二苯乙烯衍生物(M2),其结构经~1H NMR,^(13)C NMR和FT-IR表征。采用量子化学计算法,UV-Vis和FL研究了M1和M2的光学性质。结果表明:M1具有较强的ICT和明显的溶剂生色性质;M1的HOMO和LUMO轨道电子云分离明显,带隙较窄。A novel D-π-A type cyanostilbene derivative（ M1） was synthesized by Knoevenagel reaction and Williamson reaction,using 4-（ diethylamino） salicylaldehyde and 4-nitrophenylacetonitrile as materials. A novel D-π-A-D type cyanostilbene derivative（ M2） was obtained by reducing nitro to amino from M1,using Na_2 S as the reducing agent. The structures were characterized by^1 H NMR,^（13）C NMR and FT-IR. The properties of M1 and M2 were investigated by DFT calculation method,UV-Vis and FL. The results indicated that M1 exhibited stronger ICT and solvatochromism performance with obviously separating HOMO/LUMO orbit electron cloud and narrow band gap.
