【摘要】 金属有机框架材料（MOFs）在荧光识别、气体的吸附分离、电化学、催化、磁性、药物载体等方面均表现出优异的性能。^[1-4]MOFs材料作为一种新兴的荧光探针材料,克服了传统检测方式操作不便、价格昂贵、易受干扰等缺点,具有廉价、便于观察、选择性好、灵敏度高、检测限低等优势。通过荧光信号的变化可以用来检测溶液中含有的环境污染物、阴阳离子、爆炸物、生物分子等。本论文利用金属盐CdCl₂和5-（2’,5’-二羧基苯基）烟酸配体（H₃DCPN）在溶剂热条件下反应,得到了具有一维孔道结构{Cd₆（DCPN）₄ （H₂O）₄}_n晶体材料,发现其对几种常见的芳香硝基爆炸物具有很好选择性识别作用,其中对间硝基苯（DNB）的淬灭效率达到了96.3%,表明该材料能够选择性识别DNB。更多还原

【Abstract】 MOFs have been applied to fluorescence recognition, gas adsorption and separation, electrochemistry, catalysis, magnetism, drug carrier and so on. [1-4] Metal organic frameworks(MOFs) are a new fluorescent probe material. It overcomes the shortcomings of traditional detection methods such as inconvenience in operation, high price and susceptibility to interference. It has the superiority of low cost, easy observation, good selectivity, high sensitivity and low detection limit.The superiority of fluorescence enhancement or quenching can be used to detect environmental pollutants, anions and cations, explosives, biological molecules and so on. Solvothermal reaction of 5-(2′,5′-dicarboxylphenyl)nicotic acid(H3DCPN) ligands and metal salt CdCl2 affords the framework complex{Cd6(DCPN)4(H2O)4}n. It has good recognition effect on several common aromatic nitro explosives, and its quenching efficiency for m-nitrobenzene(DNB) reaches 96.3%.更多还原
