a Guests investigated in this work, including those that were previously reported by the Nitschke group57,58,59,60 and the four new bicyclic guests. b Schematic illustration of the strategy for investigation of the host-guest chemistry of MOC@PILs. c 19F NMR (D2O, 470 MHz, 298 K) spectrum of MOC@PIL 1 in the presence of an excess of fluorobenzene. d 1H NMR (D2O, 400 MHz, 298 K) spectra of the anionic cage, benzene⊂MOC, and norbornadiene⊂MOC released from MOC@PIL 6 or (guest⊂MOC)@PIL 6 by adding an excess of NaNO3.
