摘要近年来，金属有机骨架(Metal-Organic Frameworks, MOFs)材料也称多孔配位聚合物，是由金属离子或离子簇与有机连接体通过配位作用构筑而成。
它具有大的比表面积、高度可设计的骨架、可调节的孔道尺寸及内表面物理化学性质，因而在气体吸附和分离、气体存储、催化、离子交换、磁性等领域展现出广泛的应用前景。
研究表明，适当地选择金属离子或离子簇和有机配体，可以设计得到具有特定拓扑结构及性能的MOFs 材料。
芳香羧酸类配体由于其配位能力强、配位方式灵活等特性，而常被选作有机配体用于构筑MOFs。
本课题主要是合成一种用于构筑MOFs的配体3-硝基-4-(4′-吡啶基)苯甲酸。

The interests arise not only from their large pore surface areas, highly designable frameworks, tunable pore size and inner surface properties, but also from their promising applications in selective gas adsorption and separation, gas storage, catalysis, ions exchange, magnetism, and so on. So far, numerous researches on MOFs have indicated that some MOFs with specific topologies and properties can be designed by the judicious selection of metal ions and organic ligands.Aromatic multicarboxylic acids have been usually adopted as organic linkers, owing to their high affinity with metal ions and rich coordination modes.This subject is mainly to synthesis 3-nitro-4-(4'-pyridyl) benzoic acid as ligand , which was used for building the MOFs. KEYWORDS: Metal-organic frameworks (MOFs); Aromatic multicarboxylic acids; synthesis; 3-nitro-4-(4'-pyridyl) benzoic acid综 述1.1课题简介 本课题是3-硝基-4-(4'-吡啶基)苯甲酸的合成。
