Biaxial Nematic Mesophases from Shape-Persistent Mesogens with a Fluorenone Bending Unit

Line up! Two optical axes in nematic phases make high demands on the mesogen design. V‐shaped, shape‐persistent fluorenone nematogens have been shown to assemble in low‐temperature nematic liquid‐crystal phases with biaxial order (see figure).
