合成了一种由Zn_4 O（bdc）（bpz）（2）构成的三维多孔金属有机骨架[Zn_4 O（bdc）（bpz）（2）]中心点4DMF-6 H（2）O（1）（bdc = 1，4-苯二甲酸酯，bpz = 3，3 '，5，5'-四甲基-4，4 '-联吡唑），并对其结构进行了表征. N-2吸附测量显示1显示出高孔隙率，具有1908 m2/g的Langmuir表面积和0.58 cm 3/g的孔体积。化合物1具有疏水通道，其自由通道由来自bpz的甲基限定，接近8.2埃，并且它对苯和甲苯表现出良好的吸附能力，对甲醇表现出有趣的两步吸附行为。与此同时，1还表现出有趣的与客相关的发光性质。
A three-dimensional, highly porous metal-organic framework [Zn4O(bdc)(bpz)(2)]center dot 4DMF-6H(2)O (1) (bdc = 1,4-benzenedicarboxylate, bpz = 3,3',5,5'-tetramethyl-4,4'-bipyrazolate) constructed by Zn4O clusters with bdc and bpz linkers, has been prepared and structurally characterized. The N-2 sorption measurements reveal that 1 exhibits high porosity with a Langmuir surface area of 1908 m(2)/g and a pore volume of 0.58 cm(3)/g. Compound 1 features hydrophobic channels with a free passage of similar to 8.2 angstrom defined by the methyl groups from bpz, and it exhibits nice sorption capability for benzene and toluene and interesting two-step sorption behavior for methanol. Meanwhile, 1 also exhibits interesting guest-dependent luminescent properties.
