摘　　要：本文以缬氨酸/水杨醛合成Schiff碱,进一步合成镍配合物,并对其红外光谱、荧光光谱和紫外光谱进行了研究,结果表明N i(Ⅱ)配合物中,配位数为6,成双聚体结构;相对荧光强度在486 nm达到最大,发出蓝绿光;因为金属离子的微扰,将引起配位体吸收波长和强度的变化;变化与成键性质有关,与配位键结合,紫外吸收变化非常明显。In this article, the schiff base Ni （ Ⅱ） complex was synthesized by Valine and Salicylaldehyde, and its spectrum properties, such as IR, fluorescence and UV spectrums, were researched. The results showed that the complex was di -ligands structure, with cyan light at the wave of 486nm; and the UV absorbance intensity and km of complex became little or shorter than one of ligand due to the induce of Ni（ Ⅱ ）.
