以4，4 ′-（4，4 ′-联吡啶-2，6-二基）二苯甲酸（bpydbH 2）、3-氨基-1，2，4-三氮唑（Hatz）和Zn（NO3）2. 6 H2O为原料，采用溶剂热法合成了一种新型多孔金属有机骨架化合物{[Zn 3（bpydb）2（atz）2（DMF）]（DMF）6}n. X射线单晶结构分析表明，化合物1是由一维螺旋状的三唑锌配体链单元通过去质子化的bpydbH 2配体连接形成（3，4，6）-连接网络。由于化合物1具有较强的荧光发射和较高的孔隙率，可作为一种化学传感器，对水中的Fe 3+离子具有较高的选择性和灵敏度。与此相关，检测机制和主客体相互作用也通过计算分析进行了研究。
A new highly porous metal–organic framework, namely {[Zn3(bpydb)2(atz)2(DMF)](DMF)6}n, was solvothermally synthesized using 4,4′-(4,4′-bipyridine-2,6-diyl) dibenzoic acid (bpydbH2), 3-amino-1,2,4-triazole (Hatz) and Zn(NO3)2·6H2O as the starting materials. Single crystal X-ray structural analysis shows that compound1is composed of 1D helical Zn-triazolate chain building units that connected by the deprotonated bpydbH2ligand to form a (3,4,6)-connected net. Due to its strong fluorescent emission and high porosity, compound1could behave as a chemosensor for selective detection of Fe3+ion with high selectivity and sensitivity in water. In connection to this, the detection mechanism and the host–guest interaction have also been investigated via computational analysis.
