在溶剂热条件下成功地构建了一个独特的三维锌（ii）-dpbt骨架，其分子式为{[Zn 6Cl 6（2，2 '-dbpt）（3）]中心点4.5H（2）O}（n）（1）（这里2，2'-H（2）dpbt = 5，5 '-二（吡啶-2-基）-3，3'-二（1，2，4-三唑））.通过单晶X射线衍射、元素分析、粉末X射线衍射、红外光谱、热重分析、发光光谱、紫外-可见光谱、EDS和ICP-MS等手段对配合物进行了表征。并探讨了1在一系列阳离子和阴离子中的发光性能。重要的是，荧光实验表明，1是一种灵敏、有效和可快速再生的荧光探针，可用于检测Cu ~（2+）、Ag ~+、MnO（4）（-）和Cr（vi）（Cr（2）O（7）（2-）和CrO ~（4 2-））离子。
A unique three-dimensional zinc(ii)-dpbt framework with formula {[Zn6Cl6(2,2 '-dbpt)(3)]center dot 4.5H(2)O}(n)(1) (here, 2,2 '-H(2)dpbt = 5,5 '-di(pyridin-2-yl)-3,3 '-bi(1,2,4-triazole)) has been successfully constructed under solvothermal conditions. This complex was fully characterizedviasingle-crystal X-ray diffraction, elemental analysis, powder X-ray diffraction, infrared spectroscopy, thermogravimetric analyses, luminescence spectroscopy, UV-vis spectroscopy, EDS and ICP-MS. The luminescence properties confirm that the emission behavior of the Zn(ii) complex exhibits excellent thermal and chemical stabilities. The luminescence performance of1in a series of cations and anions was also explored. Importantly, the luminescence experiments reveal that1is sensitive, efficient and can be quickly regenerated (at last 4 cycles) as a fluorescent probe for detecting Cu2+, Ag+, MnO(4)(-)and Cr(vi) (Cr(2)O(7)(2-)and CrO42-) ions.
