| 摘要: 选用1，2-二苯氧基乙烷取代的氮氧双自由基（BNPhOEt）与稀土金属反应，得到了2例氮氧双自由基-稀土配合物[Ln（hfac）3（BNPhOEt）]·C6H14（Ln=Tb（1）、Ho（2）；hfac=六氟乙酰丙酮），其均为2p-4f一维链状结构。磁性研究表明，在配合物1和2中分别存在铁磁和反铁磁耦合。此外，对2个配合物的荧光光谱进行了研究分析。 |

| Abstract: The rational design of 2p-4f chains, which are made of 4f ions and nitronyl nitroxide biradical, has been presented. The reaction of Ln(hfac)3·2H2O (hfac=hexafluoroacetylacetonate) and nitronyl nitroxide biradical BNPhOEt (BNPhOEt=1,2-(bis-2,2'-(4,4,5,5-tetramethylimidazolyl-1-oxyl-3-oxide) phenoxy)ethane) afforded two isostructural chains of the formula[Ln(hfac)3(BNPhOEt)]·C6H14 (Ln=Tb (1), Ho (2)). Direct-current magnetic susceptibility studies show ferromagnetic 4f-radical interaction in Tb complex while antiferromagnetic interaction in Ho derivative. In addition, the luminescence emission spectra of two complexes vary depending on lanthanide ion. |
