[In this study, it systemically introduced a new synthetic procedures to synthesize a novel hydrophobic hard O and soft N donor combined ionic liquid ((IL-TPTNA)+NTf2-). (IL-TPTNA)+NTf2- had a TPEN analogue structure, it showed a good extraction performances of trivalent lanthanides in nitric acid solution. Then, various spectra studies revealed its stability constants and existence conditions in either aqueous or organic phase. Furthermore, based on the results of X-ray crystallography and EXAFS analyses, it found that lanthanide ions formed a 1:1 complex with (IL-TPTNA)+NTf2-. And both the hard O donor and soft N donor were involved in the formation of this complex, which is consistent with the objective of this research.]

[In本研究系统地介绍了一种新型疏水性硬O和软N给体复合离子液体（（IL-TPTNA）+NTf 2-）的合成方法。（IL-TPTNA）+NTf 2-具有TPEN类似物结构，在硝酸溶液中对三价镧系元素表现出良好的萃取性能。然后，各种光谱研究揭示了其在水相或有机相中的稳定常数和存在条件。X射线晶体学和EXAFS分析结果表明，镧系离子与（IL-TPTNA）+NTf 2-形成1：1的配合物。同时，硬O供体和软N供体都参与了配合物的形成，这与本研究的目的是一致的。
