摘　　要：以2,4-二氯苯氧乙酸为第一配体、1,10-菲罗啉为第二配体,合成了钐、铕的二元、三元配合物。通过元素分析、EDTA络合滴定及热重分析,确定了配合物的通式为RE(DCP)3.H2O,RE(DCP)3phen(RE=Sm,Eu;DCP=2,4-二氯苯氧乙酸根;phen=邻菲罗啉);测定了配合物红外光谱、紫外光谱、荧光光谱;研究了配合物的热稳定性。结果表明,三元配合物较二元配合物稳定;Eu(DCP)3.H2O和Eu(DCP)3phen具有荧光性能。The binary and ternary complexes of samarium,europium were synthesized with 2,4-dichlorophenoxyacetic acid as the first ligand,1,10-phenanthroline as the second ligand.According to elemental analysis,EDTA complexometric titration and TG-DTG,the molecular formula was determined to be RE（DCP）3 · H2O,RE（DCP）3phen（RE=Sm,Eu;DCP=2,4-Dichlorophenoxyacetic acid ion;phen=1,10-phenanthroline）.Its structure was characterized by IR,UV;and the fluorescence spectra of the complexes were measured.The results indicated that RE（DCP）3phen had better thermal stability than RE（DCP）3 · H2O,Eu（DCP）3 · H2O and Eu（DCP）3phen had fluorescence performance.
