To develop an organic heat transfer material (HTM) films with outstanding thermal conductivity, disc-shaped reactive mesogen (DRM) and cross-linker were newly synthesized. The DRM HTMs polymerized at LC phase exhibited high thermal conductivity due to the highly ordered LC structure. In addition, the heat transfer behavior of the HTM films can be adjusted using strong magnetic field. When the DRM HIMs were macroscopically oriented under the magnetic fields, the columnar axes of DRM were aligned perpendicular to the magnetic field direction. The uniaxially aligned DRM HIM films exhibited outstanding thermal conductivity as well as good mechanical and chemical stabilities.
