Synthesis, structure and physical properties of supramolecular dielectric materials

研究の背景 Background

Supramolecular dielectric materials, formed through non-covalent interactions like hydrogen bonding and π-π stacking, offer tunability and multifunctionality compared to traditional dielectric materials. They hold promise for applications in electronic devices, sensors, and energy storage. Research focuses on designing molecular units and assembly methods to control properties such as dielectric constant and thermal stability. Future studies aim to explore new molecular structures, optimize assembly processes, and enhance material performance. Advanced characterization techniques and theoretical simulations will help reveal the mechanisms behind these materials, driving their application in high-tech fields.

研究の目標 Outcome

My research goal is to design and synthesize supramolecular multiferroic materials. Specifically, I plan to incorporate crown ethers and their derivatives, as well as the self-assembly properties of organic ammonium ions in the molecular design to achieve ferroelectricity. Simultaneously, I aim to realize ferromagnetism by introducing a honeycomb oxalate layer. Through this multifunctional molecular design and self-assembly strategy, I expect to develop supramolecular multiferroic materials with excellent performance for applications in sensors, information storage, and multifunctional devices.
