摘要:

基于含氮杂环配体的金属配位聚合物的独特性能，以取代位置不同的苯二酚、萘二酚、萘醌和蒽醌为起始原料，与1,2-二溴乙烷反应生成芳烃的双溴取代物，然后再与咪唑在碱性条件下发生取代反应，合成得到六种含芳香环的双咪唑类配体（Ⅰ—Ⅵ）．结果表明，所有产物的结构均经熔点、IR、1H NMR和元素分析表征，所得数据与结构完全吻合，并对配体Ⅲ与Zn(NO3)2·6H2O形成的配位聚合物晶体结构进行了测定．

Abstract:

Based on the unique properties of coordinated polymers formed by the coordination between metal and nitrogen heterocycle ligand, six bis-imidazole ligands (Ⅰ—Ⅵ) containing benzene, naphthalene or anthracene were synthesized using hydroquinone, resorcinol, naphthalene-1,4-dione, naphthalene-1,5-diol, anthracene-9,10-dione or anthracene-1,4-dione as starting materials. All the products were confirmed by melting point, IR, 1H NMR and element analysis. It provided a premise to study the effect of aryl system on the properties of coordinated complex. A novel metal-organic framework supermolecule formed by the reaction between ligand Ⅲ and Zn(NO3)2·6H2O. Its structure was characterized by IR, TG-DSC analysis and X-ray single crystal diffraction.
