Fig. 1. Top: Imine-based dynamic combinatorial libraries in water of dialdehyde A and aliphatic diamine Bn (10 mM each, n = 4–9). Bottom: Overall conversion (grey dotted line), total yield of imine products (blue line) and of [2]catenanes Cn (red line) plotted as a function of n. These values were measured from the integration of the 1H NMR signals (internal standard: hydroquinone). Insert: zigzag representation of odd- and even-numbered aliphatic chains within a macrocycle.
