  Novel supramolecular side-chain banana-shaped liquid crystalline (LC) polymer complexes AmBn-N bearing various (m/n) molar ratios of hydrogen- and covalent-bonded bent-core components were acquired by the free radical polymerization, where the hydrogen-bonded (H-bonded) structures were executed via mixing equimolar portions of proton donor (H-donor) polymers AmBn (homopolymers/copolymers) and pyridyl proton acceptor (H-acceptor) bent cores (small molecules). The influences of the molar ratios of bent-core H-bonded components in side-chain banana-shaped LC polymers and their corresponding polymer complexes on mesomorphic and electro-optical properties were first investigated. The voltage-dependent antiferroelectric properties of spontaneous polarization (Ps) values in the polar smectic phase of the supramolecular side-chain banana-shaped copolymers were also reported. The nematic and tilted smectic phases were verified by XRD measurements, and the SmCp phase was further confirmed by the triangular wave method. Suprinsingly, a novel enantiotropic polar smectic (SmCPA) phase was generated in some bent-core side-chain polymer complexes AmBn-N. Therefore, a special approach to constructing (or stabilizing) the SmCP phase was first developed in this study by copolymerization of bent-core covalent - and H-bonded units in side-chain polymer complexes (with proper m/n molar ratios of 16/1 and 10/1 from both bent-core covalent- and H-bonded monomers (i.e., B and A-N units, respectively) without the SmCP phase.

  The synthesis and mesomorphic properties of unsymmetrical five-ring bent-core compounds containing a fluorine substituent in one of the arms are reported. A comparison of the properties with the symmetrical compounds having two fluorine substituents indicates that the position of this substituent has an influence on the nature of the mesophase observed. Evidence for the occurrence of a transition from the rectangular columnar (B1) phase to an antiferroelectric lamellar (B2) phase, which is rather rare, is provided. The mesophases have been characterized using polarized light microscopy, differential scanning calorimetry, X-ray diffraction and electro-optical studies.
