摘 要:用硅烷偶联剂修饰配体,得到含酰胺基和羧基的分子桥连中间体,中间体与正硅酸乙酯发生水解和缩聚反应,并与稀土离子配位得到分子型稀土杂化发光材料.用核磁共振光谱、红外光谱、紫外光谱、热重分析、荧光光谱和扫描电镜等手段,对该材料进行了结构表征和性能测试.结果表明:该材料具有良好的发光性能,且结构均匀,热稳定性好.A molecular bridge intermediate with amid and carboxylic group was prepared by modifying ligand with silane coupling agent.Subsequently,using their amide and carboxylic group coordinated to lanthanide ion,lanthanide luminescent molecular-based hybrid materials have been constructed from the cohydrolysis and copolycondensation process with the two similar alkoxy groups of both molecular bridge and tetraethyl orthosilicate(TEOS).NMR,FT-IR,UV,TG,SEM and fluorescence spectra were applied to characterize the properties of the obtained hybrid materials.The results showed that the materials,with good luminescent properties and thermal stabilities,are uniform lanthanide luminescent molecular-based hybrid materials.
