Hydrothermal Synthesis of Porous MOF Based on the 5-Nitroisophthalic Acid and Cu

过渡金属–有机骨架(MOFs)由于孔道和特定的荧光性能而得到广泛应用。本论文利用吡啶羧酸类配体5-硝基间苯二甲酸和金属Cu，利用溶剂热反应，构筑了一个新的稳定的三维MOF孔道材料。结构分析表明该配合物属三斜晶系，空间群为P-1，a = 11.674(5) A, b = 11.752(5) A, c = 17.213(7) A, α = 102.093(5)˚, β = 102.282(5)˚, γ = 104.251(5) (10)˚, V = 2149.1(16) A3。利用红外分析探讨了配体与框架的相互作用。红外分析表明羧基完全配位，框架具有稳定性，有可能会成为一个良好的稳定MOF。 Transition metal-organic frameworks (MOFs) have been widely used because of their specific channels and fluorescent properties. In this paper, pyridine carboxylic acid ligands 5-nitroisophthalic acid and transition element Cu thermal reaction with a solvent have been used to build a new stable three-dimensional porous MOF. Structural analysis shows that the compound belongs to the triclinic system, space group P-1 a = 7.5098(7) A, b = 8.0763(7) A, c = 10.1827(9) A, α = 71.6730(10)˚, β = 84.2690(10)˚, γ = 84.2690(10)˚, V = 554.07(9) A3. The MOF framework interac-tion and stability has been explored by using IR analysis.
