Mechanophores are compound whose color changes due to chemical bond dissociation, molecular arrangement change and photonic crystal structure change due to mechanical force. It can be applied as a sensor and self-reporting material by using a characteristic that changes color in response to mechanical stimulation. Among various mechanopores, systems whose color changes due to dissociated bonds include spiropyrans, naphthopyrans and anthracene-based materials. In this study, we designed a molecular structure capable of self-reporting by designing a molecular structure whose optical properties change due to the dissociation of covalent bonds. The introduction of mechanopores into adhesives will act as a damage sensor. The molecular structure and properties of the mechanopores were characterized by NMR, UV-vis, ESR and PL, and the color change through impact test were also studied. |
