Protonation‐Induced Transition between Two Distinct Helical Conformations of a Synthetic Oligomer via a Linear Intermediate

Abstract

Extensions and compressions on the molecular scale: A synthetic oligomer unfolds from a helical to a linear conformation upon partial and selective protonation and refolds into another helical conformation upon further protonation (see scheme).
