    • n), may possess a helical conformation different from that of the poly- 1L in toluene and benzene at low temperatures, but with a negligibly small helical sense excess, thus showing very weak ICDs. This speculation is supported by the facts that the poly- Aib and poly- 1L possess rigid rodlike features in dilute toluene because their persistent lengths estimated in dilute toluene are extremely high, 126 and 89.6 nm at 25 °C, respectively (6b, 9b)
