The enantioselective recognition of these receptors with various carboxylic acids has been studied by H-1 NMR and UV/Vis spectroscopy. The receptors exhibited different chiral recognition abilities towards the enantiomers of racemic materials and formed 2 : 1 or 1 : 1 complexes between host and guest. It was also demonstrated that chiral calix[4]arenes 9 and 16 could be used as chiral NMR solvating agents to determine the enantiomeric purity of mandelic acid.en10.1039/c0ob00399ainfo:eu-repo/semantics/closedAccessArticle9257158021063630Q1WOS:000285749800034Q1
