摘　　要：席夫碱主要是指含有亚胺或甲亚胺特性基团(-RC=N-)化合物,席夫碱配体与金属反应形成金属配合物,研究席夫碱配体与金属反应的紫外光谱特征,分析席夫碱配体金属配合物在温和条件下的低氧化性能,优化液晶材料制备。通过实验分析方法分析席夫碱配体金属配合物性能,对金属/金属氧化物纳米粒子进行金属离子固相萃取,采用ATR作为紫外光谱四氢吡喃酮衍生端,将Au沉积物(1.286 g)溶解在50 m L的HAuCl_4(1.04 mmol·L-1)中进行晶体的制备,研究席夫碱配体与金属反应的紫外光谱特征。实验结果表明,通过该制备和实验方法能准确测量席夫碱配体金属配合物与金属反应紫外光谱特征,提高了席夫碱配体金属配合物在温和条件下的低氧化性能,为优化液晶材料制备奠定基础。Schiff base is mainly refers to contain compounds of imine or azomethine group (-RC=N-) and Schiff base ligands and metal reaction forming metal complexes, seats of Schiff base ligands and metal reaction of ultraviolet spectrum characteristic. Analysis Schiff base metal complexes under mild conditions of low oxidation performance and optimization of liquid crystal materials preparation. Through experimental analysis method analysis of Schiff base metal complexes performance and on the metal/metal oxide nanoparticles of metal ions with solid phase extraction, using the ATR as derivative UV spectra tetrahydro pyrone end, Au deposits (1.286 g) dissolved in 50 mL of HAuCl4 (1.04 mmol ·L -1) of crystal preparation and research seats Schiff base ligands and metal reaction of ultraviolet spectral features. Experimental results show that, through the preparation and experimental method to accurate measurement of Schiff base ligands metal with UV spectrum characteristic of metals and reaction, improve the Schiff base metal complexes under mild conditions low oxidation performance, optimization of liquid crystal material preparing to lay the foundation.
