Metallodynamers: Neutral Dynamic Metallosupramolecular Polymers Displaying Transformation of Mechanical and Optical Properties on Constitutional Exchange

Abstract

Mix and match: Neutral dynamic metallosupramolecular polymers (metallodynamers) derived from acylhydrazone-based metal coordination centers exchange and reshuffle their components through ligand exchange at the metal coordination site, even in the absence of solvent and catalyst, to modify their constitution. As a result, the materials undergo remarkable changes in both their mechanical and optical properties (see picture).
