| 中文摘要: |
| 用缩合氧化反应，成功合成了一个新的咪唑羧酸配体2-(4’-羧基苯基)咪唑-4,5-二羧酸(H4CPhIDC)。在水热条件下以H4CPhIDC为主配体，邻菲咯啉(phen)为辅助配体，合成了镉的六核金属有机配合物[Cd6(CPhIDC)(HCPhIDC)2(H2CPhIDC) (phen)6]?H2O (MOF)。H4CPhIDC配体在该配合物中呈现出不同的去质子模式H2CPhIDC2-、HCPhIDC3-、CPhIDC4-，从而形成了一个新的六核(3,3,4,5)-连接拓扑结构。测定了配体和配合物的固体荧光光谱，并用溴化乙锭荧光探针测定了配体和配合物与DNA及BSA的作用，结果表明，配合物对生物大分子的作用更强些。CCDC：969815。 |
| 英文摘要: |
| A novel imidazole carboxylic acid ligand, 2-(4’-carboxyphenyl)-1H-imidazole-4,5-dicarboxylic acid (H4CPhIDC) was prepared by condensation and oxidation reactions, and its metal-organic framework (MOF) [Cd6(CPhIDC)(HCPhIDC)2(H2CPhIDC)(phen)6]?H2O (phen=1,10-phenanthroline) was synthesized by solvothermal reaction. The H4CPhIDC ligand presents different deprotonated motifs of H2CPhIDC2-, HCPhIDC3-, and CPhIDC4- in this MOF and thus to form a new six-core (3,3,4,5)-connected topology. Meanwhile, the fluorescence properties of the ligand and the MOF in the solid state were determined. DNA and BSA binding properties of the ligand and the MOF were investigated. The results showed that the complex has much stronger interaction with biological macromolecules than the ligand. CCDC: 969815. |
