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
