title: New polyamide cryptand for anion binding.
abstract: An anion receptor derived from a tren-based amide cryptand with pyridine spacers has been synthesized and characterized. Two crystal structures are reported: the hydrochloride salt and the fluoride complex. The cryptand shows extremely high binding with fluoride ion in DMSO-d6. Both the crystal structure and solution 19F NMR data indicate an encapsulated fluoride ion with very high symmetry.
