Effects of Perturbed Symmetry: Low‐Melting Stable Mesogens Based on ortho‐Palladated Imines

Melting points and clearing temperatures of metal-containing liquid crystals can be reduced drastically if the symmetry of the ligand sphere is lowered. This is achieved in case of the dinuclear metallomesogen 1 by replacement of PdC12-azomethine by acetyl acetonate with formation of the mononuclear complex 2. The temperature range in which the mesophase exists is thereby reduced by around 100 K to 80–130°C—an exceptionally important aspect with regard to processibility.
