摘要

在杯形[4]芳烃上加入三个三齿2,6-双三唑吡啶单元，得到了一个预先组织的亲脂配体，与镧系元素结合三价锕系元素的效率提高。结合时间分辨激光诱导荧光光谱，1D和1H-15N HMQC NMR研究，可以提出配合物的结构，并提供对锕系元素选择性的见解。

A preorganized triarmed bis-triazolylpyridine-calix[4]arene with high affinity and selectivity for minor actinides for nuclear waste treatment

The incorporation of three terdentate 2,6-bis-triazolyl-pyridine units on a calix[4]arene gives a preorganized lipophilic ligand with enhanced efficiency in binding trivalent actinides over lanthanides. Combined time-resolved laser-induced fluorescence spectroscopy, and 1D and ¹H–¹⁵N HMQC NMR investigations allowed to propose the structures of the complexes and to provide insights into the actinide selectivity.
