Summary: The synthesis and characterization of a series of supramolecular polymeric complexes formed by H‐bonding interactions between benzoic acid and azopyridine derivatives are described. A series of polymeric networks have been synthesized using a polymethacrylate bearing benzoic acid units as side groups, and several polymers with azopyridine as H‐acceptor side groups. Furthermore, low‐molecular‐weight pyridine derivatives have been used to prepare an homologous side‐chain polymer, and a network with azopyridine as a non‐covalent crosslinker. Special attention was paid to the thermal and mesomorphic properties of these materials, which were studied by DSC, POM, and XRD.Micrograph of the mesomorphic melt of a sample taken at 130 °C on cooling from the isotropic state.
