Аннотация:Influence of the electrolyte nature and the cation charge on the adsorption properties of cucurbit[6]uril supramolecular complexes are established and discussed. The results show that the growth of the cation charge leads to a narrowing of the adsorption potential region of these complexes and that in the region of its positive boundary it is possible to form an adsorbate layer of supramolecular cations associated with surface-active electrolyte anions.Key Words: supramolecular complexes, cucurbit[6]uril, cucurbit[7]uril, adsorption properties, SrCl2 solutions10.1016/j.mencom.2023.04.025
