中文摘要：

4-二苯胺基苯甲醛与水合肼经醛胺缩合反应合成了一种新型的D-π-D结构化合物——N,N＇-双二苯胺苯甲醛缩连氮（1）,其结构经1H NMR,13C NMR,ESI-MS,FT-IR及元素分析表征。通过含时密度泛函理论计算,UV-Vis和单光子荧光光谱研究了1的光学性质。结果表明：1在二氯甲烷,乙酸乙酯,乙醇,乙腈和DMF中的λmax均位于300 nm和400 nm附近;1在上述溶剂中的λem分别为489 nm,466 nm,498 nm,500 nm和505 nm。

英文摘要：

A new D - π - D structural compound, 4-diphenylaminobenzaldehyde azine （ 1 ）, was syn- thesized by condensation reaction of 4-diphenylaminobenzaldehyde with hydrazine hydrate. The structure was characterized by l H NMR, 13C NMR, ESI-MS, FT-IR and elemental analysis. The optical properties of 1 were inverstigated by quantum chemical calculation, UV-Vis and one-photon fluorescence. The results indicate that λ max of 1 were about 300 nm and 400 nm in methylene chloride, ethyl acetate, alcohol, acetonitrile and DMF. λ em of 1 were 489 nm, 466 nm, 498 nm, 500 nm, 505 nm in same solvent, respectively.
