To develop high thermal conducting organic materials, porphyrin based reactive mesogens (PRM) were newly synthesized and films were fabricated by photopolymerization. Based on scattering and thermal analyses, it was realized that PRM formed various columnar structures by adjusting the molecular packing through metal core substitution. These various molecular packing were determined by the diameter of the core, thereby varying the planarity and crystallinity of PRM. As the planarity of the PRM becomes flat, the thermal conductivity of the film was enhanced. Consequentially, the PRM substituted by Zn was show the flattest molecular planarity and highest thermal conductivity. The PRM can be applied to the heat management materials.
