title: Halogen-Bond-Assisted Guest Inclusion in a Synthetic Cavity.
abstract: The confined space inside a self-assembled cage enhanced halogen bonding (XB) between iodoperfluorocarbons (XB donors) and NO3(-) anions or H2O molecules (XB acceptors), as confirmed by NMR spectroscopy in solution and by X-ray crystallography in the solid state. The cavity also bound an XB donor-acceptor pair, C6F3I3 and C6H5NMe2, in a selective pairwise fashion.
