摘　　要：近年来，希夫碱类和它们的锌化合物由于具有电致发光性能而广受关注，特别是在纯正的荧光性能和艮好的成膜性能方面尤为突出，因此，它们已成为一类良好的电致发光材料之一。本工作合成了邻香草醛缩乙二胺类希夫碱1及其锌配合物2，它们的结构通过核磁、红外和元素分析测试手段来确定，配合物2的紫外。可见吸收光谱和光致发光光谱表明，在紫外激发下，有效的能量从配体转移到金属离子。电化学带隙与紫外，可见光谱吸收边估计的带隙基本一致。结果分析表明，在365nm波长的紫外激发下，化合物2能产生强烈的蓝光发射，发射光谱最高波峰在460nm处，谱线带宽72．2nm。化合物2明亮的光致蓝光发射可用在有机电致发光器件（OLED）中。Bis-Schiff Bases and their metal complexes have attracted large interest in re.cent years due to their electroluminescent properties, especially pure fluorescence and good film formation, therefore they have become a new type of electroluminescence materials. In this paper, ethylenediamine o-vanille Schiff base 1 and its zinc complex 2 were synthesized. The structure of the ligand 1 and its compound 2 was characterized by IR and elemental analysis techniques. The UV-vis absorption and photoluminescence spectra of the compound 2 indicate that it is a blue emitter under UV radiation while the effective energy-transfer from the ligand to the central Zn^2＋ ion occurs in the complex. The electrochemical band gap is approximatively consistent with optical band gap estimated by UV-vis absorption spectral edge. The results indicated the complex 2 could emit intensive blue fluorescence with peak wavelength at 450nm and bandwidth of 73.5nm under UV excitation at 365nm, as shown in Fig.1. The complex 2 of bright blue photoluminescence can be applied as luminescent in organic electroluminescence devices（OLED）.
