a, Reaction scheme. Note the terminal MAHT functionality of the oligomers was decarboxylated by NEt3 to yield stable thioacetate products for analysis. b, Size exclusion chromatographic (SEC) analysis of the product mixtures (top to bottom: reactions catalysed by T1, T2 and T3) and of reference samples (top to bottom: disulphide 2, dimer O1, trimer O2, tetramer O3). c, 1H NMR spectra of the product mixtures from reactions catalysed by templates T1–T3 and Takemoto catalyst (CD2Cl2, selected regions, colour-coding corresponds to Fig. 4a). d, Correlation between the number of activation sites on the template and the length of the formed oligomer.
