Fig. 2.

Characteristics of alkyl amine-driven supramolecular polymerization. a Schematic representation of the extent of self-assembly dependent on the concentration of 8A. Absorption trends at 515 nm of 1.2-8A growth b at various pH, c with various equivalents of 8A, d with 0.5 eq. of 8A added in subsequent batches, e with 0.33 eq. of 8A added in subsequent batches, f with 0.5 eq. of various amines after seeding with 0.5 eq. of 8A. The translucent overlays are profiles of unseed growth or respective nAs. (Insets for c, d: respective graphs on linear scale to easily elucidate the change in lag phase and kinetics.) Arrows indicate the addition of respective nA. (For b, c, f: [1] = [2] = 1 mM, 50 mM pH = 11.0 buffer; for d, e: [1] = [2] = 0.5 mM, 50 mM pH = 11.0 buffer)
