研究の背景 Background


Organic materials have been taken advantage as new electronics with their inherent natures such as flexibility, light weight, and variety, which have been developed on the basis of intense studies on their electric, magnetic, and optical properties. However, understanding of the thermal properties of organic materials, especially their thermal transport properties, is significantly lagging behind. On the other hand, molecular dynamics peculiar to organic materials is expected to provide unique thermal transport properties differently from inorganic materials.

研究の目標 Outcome


We study thermal transport properties on two scales, organic thin film systems and single crystal systems. In the thin film system, a tripodal triptycene is used to realize the system where molecules are arranged macroscopically, which allows us to investigate the relationship between molecular dynamics and thermal transport properties at the nanoscale. In the single crystal systems, we focus on the phase transition and try to reveal how the unique dynamics caused by the phase transition are related to the thermal transport properties.
