摘要
本文合成了两类长链脂肪酸和铕的二元配合物 ,进而以邻菲罗啉作为第二配体制得三元配合物 ,是很好的光致发光物质。元素分析及FTIR光谱初步确定了结构 ,分别为Eu(L1 ) 32H2 O ,Eu(L1 ) 3phen ,Eu(L2 ) 32H2 O ,Eu(L2 ) 3phen (L1 =月桂酸根、L2 =硬脂酸根 ) ,长链脂肪酸通过羧酸双齿螯合配位。运用紫外吸收光谱和荧光光谱进一步讨论其发光机理。通过TEM电镜研究了配合物掺杂在高分子中的形貌与颗粒大小等分布情况。
The complexes having the compositions of Eu(L 1) 32H 2O,Eu(L 1) 3phen,Eu(L 2) 32H 2O,Eu(L 2) 3phen (phen=1,10 phenathroline,L 1=Dodecanoic acid,L 2=Stearic acid) were synthesized and characterized by elemental analysis and FTIR spectra.Their fluorescence spectra,UV spectra and TEM (Transmission Electron Microscope) have been investigated.The results show that the 5 D 0 7 F 1 and 5 D 0 7 F 2 transition of Eu(Ⅲ) are observed in the emission spectrum of the particles at room temperature.As good photoluminescent materials,they may be useful in the regions of EL (Electroluminescence) or macromolecule composite materials doped with rare earth.
