Mesomorphic properties of symmetric hydrogen-bonding dimers containing chalcone moiety

الملخص EN

The work involves synthesis of a new homologous series of hydrogen bonding liquid crystal dimers containing chalcone moiety.

All the prepared compounds were characterized by spectroscopic techniques such as FT-IR, 1H-NMR, 13C-NMR as well as elemental analysis.

All the synthesized dimers exhibited nematic and smectic A phase.

The mesophases behaviour and transitional temperatures were studied by polarized microscopy and differential scanning calorimetry, and are discussed the self-assemble of H-bonding donor and acceptor complexes.
