Three zinc(II) metal-organic frameworks have been solvothermally synthesized with V-shaped 1,3-bis(1-imidazolyl)benzene (bib) and 4,4'-oxydibenzoic acid (4,4'-H₂oba), namely {[Zn(bib)(oba)]∙solvents}_n (1), {[Zn(bib)(oba)]∙2H₂O}_n (2) and {[Zn₂(bib)₂(oba)₂]∙2EtOH∙H₂O}_n (3). All of them are characterized by single-crystal X-ray diffraction, infrared spectra and powder X-ray diffraction. Complex 1 presents a two-fold interpenetrating three-dimensional structure with 4-connected (6⁵.8) topology. While, complexes 2 and 3 exhibit double layer cavity and double chains based two-dimensional structure, respectively. Luminescent studies indicate that 2 and 3 display selectively sensitive to electron-deficient nitroaromatic explosives with excellent anti-interference abilities.

用V型1,3-双（1-咪唑基）苯（围嘴）和4,4'-氧二苯甲酸（4,4'-H ₂ oba）溶剂热合成了三个锌（II）金属有机骨架，即{[Zn（bib）（oba）]∙solvents} _n（1），{[Zn（bib）（oba）]∙2H ₂ O} _n（2）和{[Zn ₂（bib）₂（oba）₂ ]∙2EtOH∙H ₂ O} _n（3）。所有这些均以单晶X射线衍射，红外光谱和粉末X射线衍射为特征。配合物1呈现了具有4个连接的2互穿的三维结构（6 ⁵.8）拓扑。而复合物2和3分别表现出基于双层腔和基于双链的二维结构。发光研究表明，2和3对具有贫乏抗电子能力的缺电子硝基芳族炸药表现出选择性的敏感性。
