In order to address the tremendous need for developing efficient heat dissipating materials that are also lightweight, Jeong and colleagues carefully designed and synthesized a new series of liquid crystalline epoxy resins (LCEs) possessing epoxy side groups with cyanobiphenyl mesogenic end groups as a thermally conductive matrix, as reported on page 708. These molecular architectures enable the cured LCE to maintain its oriented LC domains formed in the uncured state due to a presence of dipole‐dipole and π – π interactions between cyanobiphenyl mesogenic end groups. Consequently, the cured LCE exhibits a high thermal conductivity of 0.46 W m −1 K −1 . (DOI: 10.1002/pola.29315 )
