Guest-dependent single-crystal-to-single-crystal transformations in porous adamantane-bearing macrocycles

Abstract

An adamantane-bearing macrocycle showed permanent intrinsic porosity and adsorption of small organic compounds in a single-crystal-to-single-crystal fashion. Guest uptake by the porous crystals gave rise to the structural transformation of the supramolecular organic framework, resulting in the change of shape and size of one-dimensional pores.
