Pillar[5]arenes, as a new intriguing class of calixarene analogues, were functionalized with ten diglycolamide (DGA) arms on both sides (rims) of the pillar framework and evaluated for their extraction behaviour towards Am(III) and Eu(III). These novel extractants exhibit excellent separation and extraction efficiency, suggesting its significant potential for nuclear waste remediation. Laser induced fluorescence experiments disclosed strong complexation of the trivalent metal ions with the pillararene-DGA ligands.
支柱芳烃作为杯芳烃的一类新型衍生物，在其柱状骨架的两侧（边缘）功能化了十个二甘醇酰胺（DGA）臂，并对其萃取 Am(III) 和 Eu(III) 的行为进行了评估。这些新型萃取剂表现出优异的分离和萃取效率，表明其在核废料修复方面具有重要的潜在应用价值。激光诱导荧光实验揭示了三价金属离子与支柱芳烃-DGA 配体的强配位作用。
