Abstract
The formation of double hydrogen bonds between a 2,6-bis(acylamino)pyridine group and a benzoic acid moiety in the side-chain of polyacrylates or a po lymethacrylate leads to the induction of a mesophase. Monotropic mesophases are observed for these complexes below about 120 degrees C. The growth of dendritic textures at the isotropic-mesomorphic transition is seen for a po lymeric complex under polarizing microscope observation, which suggests tha t these complexes show a hexagonal mesomorphic phase.
