Abstract Since the amount of heat accumulation is proportional to the power density, the effective heat management is important to improve the reliability and lifetime of devices. For the fabrication of advanced heat transfer organic materials, we synthesized triphenylene-based reactive discogens 2,3,6,7,10,11-hexakis(but-3-enyloxy)triphenylene (HBOTP) and 4,4′,4″,4‴,4⁗,4⁗′- (triphenylene-2,3,6,7,10,11-hexaylhexakis(oxy))hexakis(butane-1-thiol) (TPHBT) as discotic liquid crystal monomers and cross-linkers, respectively. Based on the temperature−composition phase diagram of HBOTP-TPHBT mixtures and the physical, chemical, and thermal properties of Triphynylene-based heat transfer reactive discogens(TP HTRDs), the optimum content of HBOTP was determined. the TP HTRDs were polymer-stabilized by UV-irradiation at 80 °C. The TP HTRDs with outstanding thermal conductivities as well as with excellent mechanical and chemical stabilities can be applied as heat dissipating materials in electronic, automobile, and display industries. This work was supported by the BK21 Plus, the BRL 2015042417, and Mid-Career Researcher Program (2016R1A2B2011041).
