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.

Abstract: Disclosed are an interstitially mixed self-assembled monolayer (ImSAM) that can be manufactured very easily by utilizing a novel method of manufacturing supramolecular alloys called “repeated surface exchange of molecules (ReSEM)”, maintain chemical functional groups exposed to the surface of conventional thin films and selectively improve stability without interfering with performance, and a method of manufacturing the same. The interstitially mixed self-assembled monolayers (imSAMs) remarkably enhance electrical stability of molecular-scale electronic devices without deterioration in functions and reliability, withstand a high voltage, and exhibit better stability than a single SAM while maintaining the performance of the prior art, thus being useful for a variety of technical fields using SAMs, especially electronics, organic light-emitting displays (OLEDs), solar cells, sensors, heterogeneous catalysts, frictional electricity, cell growth surfaces, and heat transfer control films.

Abstract: Disclosed is a molecular diode using the assignment of electrical properties to inactive organic molecules when a self-assembled monolayer (SAM) thin film including an electrically inactive organic molecule is formed without synthesizing a separate organic molecule having electrical activity. The disadvantage of the instability of a conventional SAM can be overcome, a function can be extended, and electrical properties, such as a rectification characteristic in a non-functional molecule, can be induced even without the design and synthesis of organic molecules for introducing a functional molecule. Accordingly, the embodiments of the present disclosure can be usefully used in various technical fields in which an SAM is used, in particular, wide fields such as electronics, an organic display (OLED), solar cells, sensors, non-uniform catalysts, frictional electricity, cell growth surfaces, and a heat transfer control film.
