| 中文摘要: |
| 金属有机骨架(metal organic frameworks，MOFs)材料作为一种新型的晶型多孔材料，已经被广泛地应用于催化、仿生、荧光、化学传感、气体吸附与分离等领域．通过溶剂热法合成了一新型的以二苯胺四羧酸(TDPC)为桥连配体，以双核锌为金属节点的锌金属有机骨架Zn-TDPC，［Zn1.33(TDPC)(EtOH)］n产量高达52%．通过单晶衍射分析可以看出Zn-TDPC的框架有一个大的四边形孔道和一个小的四边形孔道．并且通过后续的单晶衍射分析、元素分析、粉末X射线衍射、红外光谱、紫外 可见光谱，以及热重分析等一系列表征可以初步判断出该MOF材料为一种全新的MOF结构，易于合成且拥有超高的稳定性，在催化、气体吸附与分离等领域存在广泛的应用前景． |
| 英文摘要: |
| As a new type of crystalline porous material, metal organic frameworks (MOFs) have been widely used in the fields of catalysis, bionics, fluorescence, chemical sensing, gas adsorption and separation. A new type of metal organic framework Zn-TDPC (TDPC=diphenylamine tetracarboxylic acid) with TDPC as the bridging ligand and binuclear zinc as the metal node is synthesized by solvothermal method and the yield of ［Zn1.33(TDPC) (EtOH)］n is as high as 52%. It can be seen from the single crystal diffraction analysis that the frame of Zn-TDPC has a large quadrilateral channel and a small quadrangular channel. And through subsequent analysis such as single crystal diffraction analysis, EA, powder XRD, IR, UV-Vis and TGA, it can be preliminarily judged that the MOF material is a new MOF structure, which is easy to synthesize and has ultra high stability. There is a wide range of application prospects in the fields of catalysis, gas adsorption and separation. |
