Supramolecular organogelator based on Azobenzene For Light Responsive Self-assembled Wringing Gel |
| 초록 |
A macro-organogelator based on azobenzene (AZO) and three biphenyl derivatives (3B) with 1,4-phenylenediformamide core was designed for wringing gel. In bulk state, AZO-3B was formed layered superstructure driven by the intermolecular hydrogen bonds and spacing-filling. But the AZO-3B formed a three-dimensional (3D) network organogel in solution. The 3D organogel was compressed by UV light and the 3D network was transformed into layered morphology. It was driven by photoisomerization of the azobenzene moiety. The metastable 3D network of AZO-3B was mainly by phase separation in solution. The light responsive wringing gels can be applicable to remote-controllable sensor, and delivery system. This work was supported by Basic Research Laboratory Program (2020R1A4A1018259) and Korea Agency for Infrastructure Technology (20POQW-B152753-02). |
