title: Calix[5]arene: a versatile sublimate that displays gas sorption properties.
abstract: Varied temperature sublimation of calix[5]arene results in the formation of two distinctly different crystal structures or polymorphs alpha and beta, the latter of which is based on both 'self-included' and 'back-to-back' helical arrangements of the molecule, while also being active towards CO2 sorption at room temperature and 1 atmosphere pressure.
