摘　　要：以辛酰基丙氨酸(H(oct-ala))、辛酰基丝氨酸(H(oct-ser))、辛酰基苯丙氨酸(H(oct-phe))化合物为配体,采用溶液化学反应法合成了辛酰基类氨基酸锌配合物,通过元素分析、红外光谱测试、核磁共振氢谱分析等方法确定目的产物的化学分子结构,并进行光吸收测试,偏光显微镜观察,XRD衍射波峰分析,SEM表面形貌观察以及纯溶剂中的溶解度测试。结果发现三种锌配合物在紫外光区域(200~300 nm)具有良好的光吸收能力,在熔融状态下表现出明显的光学异性,具有液晶性能;Zn(oct-ala)_(2)与Zn(oct-ser)_(2)具有良好的结晶趋势,在有机纯溶剂中溶解性较差;相对于以上配合物Zn(oct-phe)_(2)的溶解性较好,具有非晶化的趋势。Octyl alanine,octyl phenylalanine and octyl serine were used as ligands,combined with zinc in solution to prepared three zinc complexes respectively.The chemical structure of the complexes prepared was detected by elemental analysis,Fourier transform infrared spectrum,proton nuclear magnetic resonance and its properties were characterized by ultraviolet visible(UV-Vis)spectrum,wide-angle X-ray diffraction,polarizing microscope and scanning electron microscope.The results showed that all three complexes,especially Zn(oct-phe)_(2 ) due to its benzene ring,presented strong ultraviolet absorption in range of 200~300 nm,and obvious optical anisotropy in the molten state,characteristic of liquid crystalline.In addition,the determination revealed that Zn(oct-ala)_(2 )and Zn(oct-ser)_(2 ) exhibited better crystallinity,and poor solubility in pure organic solvent;relatively,Zn(oct-phe)_(2 )was more easily solved in the organic solvent,and more likely to be amorphous.
