Abstract: The present invention relates to a mechanophore structure of a mechanical force selectively responsive aziridine derivative and a polymer comprising same, wherein, when an aziridine derivative compound is used as a mechanophore to react to mechanical force and thermal stimulus, respectively, a covalent bond of aziridine is selectively broken by mechanical force, and thus, it has been revealed that mechanical force-only selectively responsive aziridine exists. According to the present invention, a polymer containing a mechanical force-only selectively responsive mechanophore can be manufactured, and thus can be widely used in various industrial fields such as new material fields.

Abstract: Disclosed are new polymeric materials that respond to a mechanical force. The novel polymeric compounds contain an isomer of aziridine, a three-membered N-heterocyclic compound. Also disclosed are methods for preparing the polymeric compounds. Mechanical force-induced cycloaddition of aziridines as mechanophores yields stereospecific products without covalent bond cleavage of aziridines. That is, a mechanical force makes the mechanochemical products stereospecific. The stereospecific products prepared from the isomeric mechanophores by a mechanical force can be widely used in various industrial fields, including new materials.
