合成了化合物3-(5-叔丁基-2-甲氧羰基甲氧基苯基)偶氮苯甲酸甲酯(Me2L),并以此为配体与醋酸锌在水热条件下通过自组装获得了1个二维的配位聚合物{[Zn(H2O)L]·H2O}n(1),通过红外、元素分析及X-射线单晶衍射等检测手段对所合成的化合物进行了结构表征,并测试了其荧光发射性质。相对于配位前驱体H2L的荧光发射,聚合物1的荧光发射略有红移。结构研究表明,该化合物中配体采取了常见的反式构型,形成了沿晶体学ab平面延伸的二维网状结构,聚合物中的溶剂水分子通过氢键连接在二维结构的内部。该配位聚合物的合成对于研究偶氮类配合物的光化学反应奠定了基础。
The compound 3- (5-tert-butyl-2-methoxycarbonylmethoxyphenyl) azobenzoic acid methyl ester (Me2L) was synthesized and used as a ligand with zinc acetate under hydrothermal conditions by self- A two-dimensional coordination polymer {[Zn (H2O) L] · H2O} n (1) was obtained. The synthesized compounds were characterized by IR, elemental analysis and X-ray single crystal diffraction Characterization and testing of their fluorescence emission properties. The fluorescence emission of polymer 1 is slightly red-shifted with respect to the fluorescence emission of the coordination precursor H2L. Structural studies show that the ligands adopt a common trans configuration and form a two-dimensional network extending along the ab plane of crystallography. The solvent water molecules in the polymer are connected by hydrogen bonds inside the two-dimensional structure . The coordination polymer synthesis of azo compounds for the study of photochemical reactions laid the foundation.
