Fig. 4. (a) Concentration vs. time profile and (b) rate vs. time profile for the reaction of maleimide L with stopper S, to give thread T in the absence of any added template (filled red circles/full red line) and in the presence of 38 mol% pre-formed T (empty red circles/dashed red line), added at t = 0 as determined using 500 MHz 1H NMR spectroscopy (15 °C, CDCl3). Formation of cis-T is not plotted for clarity (concentration less than 0.6 mM after 15 h).
