Denaturation curves for titration of c-P6[b6]·T6, c-P6[b5e]·T6, c-P6[be5]·T6*, and c-P6[e6]·T6* with N-methyl imidazole. θ is the mole fraction of nanoring bound to the template, estimated as θ = (A – Af)/(Ai – Af), where A, Ai, and Af are absorption, initial absorption, and final absorption, respectively. Titrations were carried out in toluene at 298 K with a nanoring concentration of ca. 1 μM.
