Abstract

Abstract : A supramolecular nanocapsule can effectively separate C78 -based EMFs over C80 -based EMFs based on the shape preference for flattened C78 -based EMFs. Abstract : The ability of the tetragonal prismatic nanocapsule 1 ·(BArF)8 to selectively encapsulate U-based C78 EMFs from a soot mixture is reported, showing enhanced affinity for C78 -based EMFs over C80 -based EMFs. Molecular recognition driven by the electrostatic interactions between the host and guest is at the basis of the high selectivity observed for ellipsoidal C78 -based EMFs compared to spherical C80 -based EMFs. In addition, DFT analysis points towards an enhanced breathing adaptability of nanocapsule 1 ·(BArF)8 to C78 -based EMFs to further explain the selectivity observed when the host is used in the solid phase.
