In heat management research, understanding the relationship between the packing structure of molecules and thermal conducting properties is important. In this research, porphyrin and dendritic alkyl chain-based reactive metallomesogens were newly synthesized. The mixture of metallomesogen and thiol molecules shows columnar structures by self-assembly, and those phases were fixed by thiol-ene click reaction. Based on thermal and scattering analysis, it was realized that the films formed each different structure by the various substituted metal atoms. These phases were determined by the diameter of the metal atoms, thereby varying the planarity and crystallinity. Consequentially, the metallomesogen film substituted by Zn exhibits the highest heat transition property. This work was mainly supported by Basic Research Laboratory Program (RS-2023-00207836).
