Combination of Chiral and Achiral Triphenylene Units in a Novel Unsymmetrical Columnar Twin

The synthesis, characterization, and mesomorphic properties of a new type of liquid‐crystalline twin bearing a pentadecyloxytriphenylene subunit tethered via a decyl spacer to a chiral pentakis(3,7‐dimethyloctyloxy)triphenylene are reported. The target compound displays a hexagonal columnar mesophase, which is metastable at room temperature.
