Two new meso-indanyl-substituted calix[4]pyrrole receptors, 2 and 3 , have been synthesized. A range of calix[4]pyrrole host-neutral molecule complexes crystallise from solutions of 2 in a variety of solvents and the structures of four have been elucidated by X-ray crystallography. The F− and Cl− anion affinities of 2 have been measured in acetonitrile, and are significantly different from the corresponding affinities of the prototypical calix[4]pyrrole, the octamethyl-derivative, 1 . ESI-FTICR-MS has been used to determine the relative F− and Cl− anion affinities of receptors 1 and 2 in methanol–acetonitrile solution. Deprotonation of 1 and 2 by fluoride is observed (under the conditions of the MS experiment). |
