“…Supramolecular π-anion interactions were evident along with electrostatic interactions due to protonation of the receptor, but poor extraction and negligible selectivity was seen from aqueous nitric acid. Similarly, a pre-organised arene/quinoline-ether tripodal receptor formed a 1:1 host:guest complex with RE(NO 3 ) 3 (MeOH) 3 in methanol through ether-alcohol hydrogen bonding interactions 24 . Pre-organised hexa-substituted arene platforms are well-known to self-assemble into supramolecular tennis-ball structures 25 , 26 , and can encapsulate simple anions such as fluoride, nitrate, and arsenate 27 – 29 .…”

Supramolecular chemical strategies for Rare Earth (RE) element separations are emerging which amplify the small changes in properties across the series to bias selectivity in extraction or precipitation. These advances are important as the REs are crucial to modern technologies yet their extraction, separation, and recycling using conventional techniques remain challenging. We report here a pre-organised triamidoarene platform which, under acidic, biphasic conditions, uniquely and selectively precipitates light RE nitratometalates as supramolecular capsules. The capsules exhibit both intra- and intermolecular hydrogen bonds that dictate selectivity, promote precipitation, and facilitate the straightforward release of the RE and recycling of the receptor. This work provides a self-assembly route to metal separations that exploits size and shape complementarity and has the potential to integrate into conventional processes due to its compatibility with acidic metal feed streams.

“…The neighbouring atoms can interact well as the alkyl chain moving towards the surface of UiO-66 [ 47 ]. These hydrogen bonds could be contributing to the host-guest interactions of IL and UiO-66 which also stabilizes the framework structure, as evidenced by the thermal analysis from DSC curves [ [48] , [49] , [50] ].…”
