To understand the correlation between the supramolecular packing structure and heat transfer properties, porphyrin-based reactive metallomesogens (PRM-n; n = -2H, -Ni, -Cu, Zn) were newly programmed and synthesized. Self-assembled and subsequently photopolymerized PRM-n films showed excellent mechanical, chemical, and thermal stabilities. As the planarity of the metallomesogen becomes flat, the thermal conducting properties of PRM-n films were enhanced. The thermal conductivity of PRM-n films is measured to be 0.88, 1.02, 0.97, and 1.2 Wm-1K-1 (PRM-2H, -Ni, -Cu, and -Zn, respectively).
