To understand the correlation between the supramolecular packing structure and thermal properties, porphyrin-based reactive metallomesogens (PRM-n; n = -2H, -Ni, -Cu, -Zn) are newly programmed and synthesized. Based on thermal and scattering results, PRM-n with different metal substitution show different molecular packing structures. Subsequently, 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). PRM-Zn exhibits columnar rectangular structure with π-π stacking so it can have denser molecular packing structure and higher crystallinity than other species.
