Abstract
Ester tub[4]arene, a conformationally adaptive macrocycle with interconvertible cavities, has been synthesized and characterized. Its conformational complexity was analyzed, and its binding ability to organic cations was studied by 1H NMR spectroscopy and UV–vis spectroscopy. The conformational conversion of the host can be achieved by binding a suitable guest. The binding performance of such adaptable receptors may have significant implications for the molecular recognition processes occurring in natural settings.
