Stable supramolecular dimer of self-complementary benzo-18-crown-6 with a pendant protonated amino arm†
Abstract
The novel 4′-(ammoniummethylene)benzo-18-crown-6 cation was synthesized as a hexafluorophosphate salt and found to exist as a cyclophane-like dimer in the solid state, gas phase and in acetonitrile solution.
