Abstract/OtherAbstract:
A novel mechanophore with acid-releasing capability is designed to produce a simple catalyst for chemical change in materials under mechanical stress. The mechanophore based on a gem-dichlorocyclopropanated indene is synthesized and used as a cross-linker in poly(methyl acrylate). Force dependent rearrangement is demonstrated for cross-linked mechanophore samples loaded in compression while the control shows no significant response. The availability of the released acid is clearly observed by adding a solution of pH indicator to a piece of insoluble compressed polymer. The development of this novel mechanophore is the first step in the conception of unique force-induced remodeling of stressed polymeric materials utilizing acid catalyzed cross-linking reactions.
