Abstract
Two or four perfluorinated alcoholic functions were successfully introduced at the upper rim of calix[4]arenes, affording a new type of neutral receptor for anion recognition; preliminary binding studies indicate that the difunctionalized receptors 3a and 3b are selective for Y-shaped carboxylate ions over spherical anions which are, on the contrary, more efficiently bound by the tetraalcohol 6.| File | Dimensione | Formato | |
