| Abstract | ||
| 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. | ||
