Metal‐containing liquid crystals offer the possibility of obtaining mesogenic materials with novel electronic properties. However, the transition temperatures need to be reduced before applications can be found. The authors describe the first fully characterized metallomesogens with an authentic columnar mesophase near room temperature, which were obtained by inserting carbon‐carbon double bonds as the “R” group in te carboxylate ligands (see Figure).
