• separation [4][5][6][7][8]. Building on the extensive research into anion and cation receptors within the realm of supramolecular chemistry [9][10][11][12], numerous heteroditopic ion-pair receptors have been elaborately developed [13][14][15]. These receptors, consisting of binding sites for both anions and

• cations within a single molecule, have facilitated advancements in ion-pair recognition. This progress has led to the development of ion separation utilizing ion-pair receptors [16][17][18][19][20], which eliminate the need for auxiliary reagents to balance overall charges compared to the use of

• individual anion or cation receptors [21]. An alternative approach for ion separation involves the combination of an anion receptor and a cation receptor, known as the dual-host strategy [22][23][24]. Unlike ion-pair receptors, this strategy avoids the intricate, multi-step synthesis required for designing
