MOF have been much studied due to their potential applications from their excellent physical and chemical properties, however, many are unlikely to realize their potential due to the expense of the starting materials and/or complexity of the synthesis involved. In this HOT article, Day and co-workers have formed stable cucurbit[5]uril MOF structures as ‘beaded’ rings built on a p-hydroxybenzoic acid template prepared readily by self-assembly as a supramolecular structure that remarkably can be recrystallised from water to form the same stoichiometry and structure as occurs under the initial crystallisation conditions. Accessible channels have clearly been demonstrated for a group of polar volatile organic molecules with significant absorption selectivity for at least three examples.
