摘要本文首先以邻苯二胺,2-氯烟酸和多聚磷酸PPA为原料制备出BMOP(BMOP=3-(1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one),再用BMOP和2,6萘二羧酸为配体与四水硝酸镉和六水硝酸锌通过溶剂热法在DMF和水的混合溶液中,温度120℃,烘3天,得到目标产物MOF-Cd和MOF-Zn。然后我们通过CCD探测仪对我们制备的两种配合物进行了晶体结构测定。在室温下,我们测得了所合成配合物的一些物理性质,相对分子质量、晶胞体积、Z值、S值、R值等晶胞参数,并且列出了所合成配合物的主要键长、键角。另外,通过实验数据我们绘出了所得晶体的配位环境图,弱相互作用图,拓扑图和堆积图。实验结果表明MOF-Cd结晶在monoclinic晶系,P21/c空间群,其晶胞参数a = 7。986(3)Å,b = 11。937(5)Å,c = 14。863(6)Å,α = 90。00°,β = 91。219(4)°,γ = 90。00°,V = 1416。6(10)Å 3;MOF-Zn结晶在tetragonal晶系,I41/a空间群,其晶胞参数a = 21。085(3)Å,b = 21。085(3)Å,c =15。287(4)Å,α = 90。00°,β = 90。00°,γ = 90。00°,V = 6769(3)Å 3。两种化合物MOF-Cd和MOF-Zn都具有荧光,发蓝光。具有荧光是受到配体BMOP的影响。87323

Abstract This paper firstly with o-phenylenediamine and 2-chloronicotinic acid and poly phosphoric acid (PPA) prepared BMOP, then BMOP and 2, 6 naphthalene dicarboxylic acid water ligands and four water cadmium nitrate and zinc nitrate by solvent thermal method in DMF and water mixed solution, temperature of 120 DEG C, bake for 3 days, obtained target product MOF-Cd and MOF-Zn。The two complexes by CCD detector for us then we prepared for crystal structure determination。At room temperature, we obtained the synthesized complexes of some physical properties, relative molecular mass, cell volume, Z value, s value, R value of unit cell parameters, and lists the synthesized complexes main bond lengths and bond angles。 In addition, through the experimental data, we draw the coordination environment map, the weak interaction diagram, the topological graph and the packing graph。 Experimental results show that MOF-Cd crystallize in the monoclinic crystal system, P21/c space group, the unit cell parameters are a =7。986 (3) Å, B = 11。937 (5) Å, C =14。863 (6) Å, alpha = 90。00 degrees, beta = 91。219 (4) ~, gamma = 90。00 degrees, v = 1416。6 (10) Å3; MOF-Zn crystallization in by crystal system, belong to I41 / a space group and the unit cell parameters are a =21。085 (3) a, B = 21。085Å and C =15。287 (4) Å, alpha = 90。00 degrees of beta = 90。00°, gamma = 90。00°, V= 6769 (3)Å3 。 MOF-Cd and MOF-Zn of the two compounds all have fluorescence, and the hair is blue。 Fluorescence is affected by ligand BMOP。
