Operating off the racemic equilibrium state. a Size comparison between 3 and the helix derived from it, as inferred from dynamic light scattering experiments. b CD spectral changes of 3 (2.5 × 10−4 mol l−1) upon the addition of AgBF4. The concentrations of AgBF4 are (i–vi) 0.0, 0.5, 1.0, 1.5, 2.0, 2.5 × 10−4 mol l−1. c CD spectral changes of 1 (2.5 × 10−4 mol l−1) seen upon the addition of AgBF4. The concentrations of AgBF4 are (i–iii) 0.0, 1.3, 2.5 × 10−4 mol l−1. d Plots of the relative CD intensity measured at 290 nm vs mole fraction of 3. At each datum point, the concentration of AgBF4 was equal to the total concentration of 1 + 3. The dotted line indicates the expected CD intensity in the absence of chiral amplification. All studies were carried out in THF
