| 摘要: 以4，4'-二（1-咪唑基）苯硫醚（BIDPT），4，4'-羧基二苯胺（H2aba），5-氧乙酸间苯二酸（H3OABDC），Zn（NO3）2·6H2O和Cd（NO3）2·6H2O为原料，用溶剂热法合成了2个配位聚合物[Zn（BIDPT）（aba）]n（1）和[Cd（BIDPT）（HOABDC）]n（2）。利用X射线单晶衍射、红外、元素分析、热重分析和X射线粉末衍射对其进行了表征。单晶X射线衍射研究发现配合物1为具有二重穿插的三维dia拓扑网络结构；配合物2为3-连接六边形的hcb二维拓扑结构，再通过氢键堆积作用形成三维超分子结构。1和2具有很好的荧光性质，硝基苯化合物对配合物1和2的荧光性质有不同程度的淬灭作用。它们都对2，4，6-三硝基苯酚的检测具有很好的灵敏性。对其淬灭机理进行了深入的研究。 |

| Abstract: Two coordination polymers, namely[Zn(BIDPT)(aba)]n (1) and[Cd(BIDPT)(HOABDC)]n (2) (BIDPT=4,4'-bis(imidazol-l-yl)diphenyl thioether, H2aba=4,4'-azanediyldibenzoic acid, H3OABDC=5-oxyacetate isophthalic acid) have been solvothermally synthesized and characterized by infrared spectroscopy, elemental analysis, and powder X-ray diffraction. In 1, the Zn(Ⅱ) ions are linked by BIDPT and aba2- ligands to give a 2-fold interpenetrating 3D frameworks with {66} dia topology. Compound 2 can be viewed as a 3-connected hcb net with the point symbol of {63} and extended into a three-dimensional supramolecule through hydrogen bonds. Complexes 1 and 2 show strong luminescence and their luminescence could be quenched by a series of nitroaromatic explosives. Importantly, they exhibit very highly sensitive and selective detection of picric acid compared to other nitroaromative explosives. The quenching mechanisms are also deeply studied. |
