Fig. 4. 1H NMR spectra in D2O of (a) A (non-labelled signals correspond to the hydrate), (b) library formed from A and B5 (10 mM each), (c) library formed from A and B7 (10 mM each), and (d) B7. Only the signals corresponding to the [2]catenanes are assigned in spectra (b and c). (e) DOSY of the library formed from A and B7 (5 mM each) in D2O. Squares, diamonds and circles refer to the labelling scheme defined in Fig. 1.
