中文摘要: 本项目在研究不同稀土中心离子间的敏化效应、稀土-过渡金属d-f异金属体系中金属离子间能量传递规律的基础上,设计合成系列特定结构的不同稀土中心离子以及稀土与过渡金属共同参与配位的同多核、异多核金属配合物,将其加载到聚氨酯丙烯酸酯大分子单体(PUAM)体系中,PUAM两端的C=C-经自由基聚合,构筑新型的具有网状结构的聚氨酯复合材料(RE/TM-PC)。研究RE/TM-PC材料体系中多配位中心离子间的敏化效应、d-f能量传递效应等,通过剪裁、协同不同建筑块的物理化学性能,赋予复合材料RE/TM-PC可见光高效敏化激发、不同波段荧光显示、吸附、磁性能等特殊功能。深入研究其光、磁、吸附及抗菌等性能,探索多金属中心离子间的协同效应与目标功能材料的构效关系,探明其中的规律性。有望开发一类新型的金属配合物/聚氨酯多功能复合材料,在基础研究与应用研究之间架起新的桥梁,具有重要的意义。

英文摘要: In this project, series of heterometallic complexes, which has specific structures constructed from the different f-block metal ions/the d- and f- metal ions and N, O-containing ligands, were designed and synthesized on the basis of the Antenna effect of ligands, the sensitization effect of different the metal center, the d-f energy transfer of the d-f heterometallic framework. With that, polyurethane composite materials (RE/TM-PC) with interconnected structure were synthesized by the free radical polymerization of the C=C- terminal groups of polyurethane acrylate macromer (PUAM). The investigation of the sensitization effect and d-f energy transfer of different central metal ions will be carried out. According to tailoring and cooperating with the physical and chemical properties of different building blocks, the composition material will be endowed with special features, such as efficient sensitized excitation in the visible region, fluorescent in the different bands, adsorption, magnetism and so forth. We shall further explore its luminescent, magnetic, absorption, and antibacterial properties, as well as summarize the structure-activity relationship between the synergy effect of different metal ions and the target function material; as such, summarizes the rules. Through research of this project, we expect t
