摘要: 以3,5-双(4-羧基苯氧基)吡啶(H2bcpp)和1,4-双(1-咪唑基)苯(1,4-bib)为配体,通过溶剂热法构筑了一个新型的热稳定性和水稳定性的Zn(Ⅱ)基金属-有机框架:[Zn2(bcpp)2(1,4-bib)2]·1.5H2O(1)。配合物1属于单斜晶系,I2/a空间群,具有一维管状结构。相邻的一维结构通过相互穿插形成一个三维超分子结构。此外,配合物1具有良好的荧光性,能够对水溶液中的铁离子及农药2,6-二氯-4-硝基苯胺实现高灵敏及高选择的荧光猝灭检测。 |

Abstract: A novel thermal-stable and water-stable Zn(Ⅱ)-based metal-organic framework (MOF), [Zn2(bcpp)2(1,4bib)2]·1.5H2O (1) was synthesized by solvothermal method based on 3,5-bis(4-carboxylphenoxy)pyridine (H2bcpp) and 1, 4 - bis(1 - imidazoly)benzene (1, 4 - bib). Complex 1 belongs to the monoclinic system with space group I2/a, which exhibits a 1D tubular structure. The adjacent 1D tubular structures are interpenetrated with each other to obtain a 3D supramolecular structure. Moreover, complex 1 exhibits excellent photoluminescence property, which can be applied as a“turn-off”fluorescence probe to detect Fe3+ ion and pesticide 2,6-dichloro-4-nitroaniline in an aqueous solution with high selectivity and sensitivity. |
Keywords: metal-organic framework Zn(Ⅱ) luminescence detecting Fe3+ pesticide |
