Reversible switching between macrocyclic and polymeric states by morphological control in a constitutional dynamic system

Abstract

(Figure Presented) Exchanging loose ends: The combination of a morphologically controlled core and reversible covalent linkages allows the reversible switching of a dynamic system between two states, a macrocyclic and a polymeric one (see picture). The process demonstrates that a constitutional dynamic system may undergo a constitutional change on modification of morphological information. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
