【摘要】:金属—有机框架(Metal-Organic Frameworks,简称MOFs)材料是一种新型的多孔有机—无机杂化材料,具有比表面积大、孔隙率高、孔道尺寸和功能界面易调节等特点。其在气体存储、吸附分离、传感、催化和生命科学等多个领域具有潜在的应用。本文合成了一系列以咔唑为母体的有机配体,并研究了它们与过渡金属离子的超分子自组装化学,利用溶剂扩散到溶剂热法组装得到了13个未见文献报道的配位化合物,通过红外、X-射线单晶衍射、粉末衍射、元素分析等表征了它们的结构,研究了部分化合物的物理及化学性质。一、合成了12例以醚键为取代基的咔唑桥联有机配体L1-L12,与过渡金属离子(M=Cu2+,Cu+,Co2+,Cd2+,Ni2+)通过溶剂扩散与溶剂热法组装得到了8例结构稳定的配位化合物。二、利用化合物1制备出几例比较新颖的电极材料。通过对其组装条件的调控,实现了该Co(II)-MOF的微纳化;通过对其组装基底的调控,成功得到了形貌均一的纳米级Co(Ⅱ)-MOF@FTO材料,并探究了该Co(Ⅱ)-MOF@FTO材料的电催化氧化性能。三、合成了2例以苄基为取代基的含N有机配体L13-L14,研究了它们与过渡金属离子的自组装化学,得到了5例结构稳定的配位化合物,通过X-射线单晶衍射表征了它们的结构。研究表明,本文设计、合成的配位聚合物拓扑结构新颖,部分化合物具有良好的功能化性质,丰富了配位化学的研究内容。
[Abstract]:Metal-Organic frameworks (MOFs) is a new porous organic-inorganic hybrid material with large specific surface area, high porosity, easy adjustment of pore size and functional interface. It has potential applications in many fields, such as gas storage, adsorption and separation, sensing, catalysis and life science. In this paper, a series of organic ligands with carbazole as parent have been synthesized, and their supramolecular self-assembly chemistry with transition metal ions has been studied. Thirteen unreported coordination compounds have been obtained by solvent-diffusion to solvothermal assembly. Their structures were characterized by IR X-ray single crystal diffraction, powder diffraction and elemental analysis. The physical and chemical properties of some compounds were studied. One, 12 carbazole-bridged organic ligands, L1-L12, which were substituted by ether bonds, were synthesized by solvent-diffusion and solvothermal method to obtain 8 stable coordination compounds. Secondly, several novel electrode materials were prepared by using compound 1. By adjusting the assembly conditions, the micronanocrystallization of the Co-III-MOF was realized, and the uniform morphology of nano-scale Co (鈪,
