摘要
制得了喹啉酮羧酸衍生物(C16H15N3O6)的稀土配合物,通过红外、质谱、热重以及电化学分析表征了它们的结构,确定了配合物的化学组成为[Ln(C16H15N3O6)X]·n H2O(Ln=Ce、Te)。之后对他们的荧光性能进行研究发现:金属铈离子形成的配合物荧光强度为配体的3.0倍,同时相比于配体,配合物的最大荧光发射波长红移33.5 nm。金属铽离子形成的配合物相比于配体最大荧光发射波长红移46 nm。且两种配合物峰形明显优于单独的存在的金属离子与配体。结果表明制得的稀土有机配合物有良好的荧光性能,在光电及离子检测领域有潜在的应用价值,对生物检测和荧光成像技术的发展具有重要意义。
Quinolinone-based rare earth complexes were synthesized from carboxylic acid derivatives of quinolinone( 1). Their structures were characterized by FTIR,TG,MS analyses,and the complexes were determined to be [Ln( C16H15N3O6) X]· n H2O( Ln = Ce,Tb). The fluorescence properties of complexes and compound 1 were investigated. The result showed that the fluorescence intensity of cerium complex( 2) was 3. 0 times as the compound 1. Meanwhile,the maximum fluorescence emission wavelength of complex 2 exhibited red shift(46 nm) compared to that of compound 1. The maximum fluorescence emission wavelength of terbium complex(3) exhibited red shift(46 nm) compared to that of compound 1. The peak pattern of the two lanthanide metal complexes was superior compared to that of compound 1 and metal ions. On the base of these results,the complexes have a good application prospect in optoelectronic field,and are significant to the technological development in biological detection and fluorescence imaging.
