| 摘 要： | 以铜试剂(NaEt2 dtc·3H2O)和邻菲咯啉(o-phen·H2O)与水合氯化稀土(RECl3·xH2O)(RE=La,Pr,Nd,Sm～Er;x=3～4)在无水乙醇中反应,制得三元固态配合物RE(Et2dtc)3(phen).IR光谱研究表明配合物中RE3+与NaEt2dtc中的硫原子和o-phen中的氮原子均双齿配位;UV光谱显示配合物中o-phen与稀土离子之间的能量传递是主要过程,配合物的最大吸收与o-phen相比有微小的红移;FS光谱表明配合物Sm(Et2dtc)3(phen)和Eu(Et2dtc)3(phen)分子内能量传递效率高,显示了很强的荧光性质.

| Abstract: | The ternary solid complexes RE(Et2dtc)3 (phen) (RE=La, Pr, Nd, Sm-Er) were synthesized with sodium diethyldithiocarbamate (NaEt2 dtc x 3H2O), 1,10-phenanthroline (o-phen x H2O) and hydrated lanthanide chlorides in absolute ethanol by improved reported method. IR results revealed that RE3+ coordinated with sulfur atoms of NaEt2 dtc and nitrogen atoms of o-phen. As for UV spectrum of the complexes, energy transfer between o-phen and RE3+ was the primary process, and the main absorption peaks showed a slight red shift compared to that of o-phen; FS spectrum, as a comparison, showed that the complexes Sm (Et2 dtc)3 (phen) and Eu(Et2dtc)3 (phen) have a higher efficiency of intermolecular energy transfer and a stronger fluorescence character. |
