Abstract

Abstract : A ligand exchange strategy was successfully utilized for tuning the response speeds of helicity induction and inversion of a metal‐containing helical structure. The helicity changes were driven by the exchange of six axial amine ligands that are introduced into the three Co 3+ centers in the metallocryptands, and the response speeds were efficiently controlled by using different combinations of the starting and entering amine ligands.
