We describe the synthesis of a new family of ferrocene-containing liquidcrystalline dendrimers. All ferrocene-based dendrimers gave rise to enantiotropic hexagonal columnar phases. The liquid-crystalline phases were characterized by Xray diffraction, differential scanning calorimetry, and polarized optical microscopy. Oxidation of the peralkylated ferrocene unit led to a loss of the...
