Cavity Strong Coupling for Material Chemistry

研究の背景 Background


By altering the energy states of molecules and their intermolecular interactions, it becomes feasible to generate novel properties in functional materials and manipulate chemical reactions. Traditional molecular chemistry has relied on the approach of designing molecules that align with desired physical properties and reactions. The utilization of external fields to modify material properties has the potential to unlock new avenues for creating novel physical properties and chemical reactions.

研究の目標 Outcome


The strong coupling of molecules in a Fabry–Perot cavity enables to alter the energy states of the molecules, leading to the control of molecular properties. Our objective is to develop methods that leverage strong coupling to generate fresh properties in functional materials, while also gaining control over chemical reactions and self-assembly processes.
