Fig. 7. Disassembly of the dimer 5·5 by competitive recognition events: (a) schematic representations of the disassembly of 5·5 in the presence of the N-oxide derivative 6; (b) partial 1H NMR spectra (400 MHz, CDCl3, 298 K) of 5 during the addition of an increasing amount of the N-oxide 6. See lettering in Scheme 1. Signals related to the fumaramide station are coloured in red. Signals related to the GlyGly station are coloured in green. Signals related to the N-oxide 6 are coloured in orange.
