我们报道了一个带有三个CMPO单元的多足配体的合成和研究，以及由此得到的Ln3+，Th4+和UO22+金属络合物。这种三脚架配体从1M的硝酸中对榄系元素Th(NO3)4和UO2(NO3)2的萃取效率分别为47%和44%，而所有稀土硝酸盐的萃取效率都相对较低。利用5M硝酸溶液进行的进一步提取研究导致了几乎定量的鳗系元素提取。研究了该配体对DMSO溶液中Eu3+和Tb3+的金属中心发光的敏化能力。最后，用密度泛函理论计算了[La(NO3)-配体]2+络合物的可能构象。
We report here the synthesis and study of a multipodal ligand bearing three CMPO units attached to a trialkylphosphine oxide cap along with the resultant Ln3+, Th4+and UO22+metal complexes. This tripodal ligand demonstrates extraction efficiencies of 47% and 44% for the actinide species Th(NO3)4and UO2(NO3)2out of 1 M nitric acid into a solution of dichloromethane, while all lanthanide nitrates were extracted with relatively low efficiencies. Further extraction studies utilizing 5 M nitric acid solutions resulted in nearly quantitative actinide extraction. The ability of this ligand to sensitize the metal-centered luminescence of Eu3+and Tb3+in DMSO solutions was also investigated. Finally, possible conformations for the structure of the [La(NO3)-ligand]2+complex were calculated using density functional theory.
