resumo
Designing efficient and stable non-precious coordination polymers remains a challenge for the luminescent sensing of enrofloxacin and acetylacetone. Three Zn(II)-coordination polymers with the formula {[Zn-2(L)(BTC) (OH)]center dot H2O}(n) (1), [Zn-1.5(L)(MIP)(OH)] (n) (2) and [Zn(L)(DBT)](n) (3); L = 2-(2-Pyridin-3-yl-vinyl)-1H-benzimidazole, H3BTC = 1,3,5-benzene tricarboxylic acid, H2MIP = 5-methylisophthalic acid, and H2DBT = 2,5-dibromoterephthalic acid were hydrothermally synthesized and characterized. 1 reveals an unusual 3D topology, 2 displays a 3D mog framework, while 3 exhibits (4,5)-connected 3D xah framework. 1 similar to 3 are firstly dualfunctional luminescence sensors for detecting enrofloxacin and acetylacetone, expressing high selectivity and sensitivity. Quick and visual detection of enrofloxacin and acetylacetone without any pretreatment is realized by using CP 1 similar to 3 paper-based sensors. Furthermore, the fluorescence sensing mechanism was discussed in detail.
