    • The ICD intensity of the poly-1c with (R)-2 in the dilute concentration region of poly-1c gradually decreased with time, while that with (R)-3 hardly changed.

    • - value is the sum of the ion pair and the free ions. Therefore, a practical amount of the ion pair to induce an almost one-handed helix on poly-1 with (R)-2 must be less than 50%. The amounts of the ion pair and free ions can be estimated by the method described in ref 41. These results together with the theoretical analyses by the Ising model will be published elsewhere.

    • note
    • It should be noted that the poly-1a fraction separated from the poly-1a-(R)-2 complex using pure DMSO as the mobile phase showed no ICD, indicating that the (R)-2 complexed with poly-1a was completely removed during the SEC fractionation, and free poly-1a cannot maintain the induced helical conformation.
