摘要: 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。

Abstract: Aligand, namely methyl 3-((5-tert-butyl-2-(2-methoxy-2-oxoethoxy) phenyl) diazenyl) benzoate (Me2L), had been designed and synthesized. Under hydrothermal condition, one coordination polymer {[Zn(H2O)L]·H2O}n(1) was obtained by using Me2L and zinc acetate. The complex 1 was characterized by IR, elemental analysis and X-ray single crystal diffraction and the fluorescence property of the complex 1 was investigated. Compared to the emission spectrum of H2L, the emission maximum of the complex 1 was red shift. The structural research revealed that the L2- adopt the trans-configuration in the complex 1 which has a 2D network extends along crystallographic ab plane. The solvent water molecule was joined into the 2D network though four sets of H-bonds. The synthesis of the complex 1 could be the foundation of the photochemistry research of the coordinate complex based on Azo ligands. CCDC: 931724.
