Résumé
We describe herein the ionic modulation of contraction /extension motions in a type of process involving the reversible switching between molecular linear quaterpyridine (3-E) and quinquepyridine (4-L) ligands and the metallosupramolecular wrapped helical-type (3-H) and double helix-type (4-DH) complexes, triggered by Pb2+ metal ion complexation-decomplexation reactions These systems represent the dynamic chemical devices undergoing ionic modulation of reversible molecular mechanical motion fuelled by acid/base neutralization.
