Synthesis and mesomorphic properties of novel phenacylpyridines and their copper (II) complexes
The synthesis, characterization and liquid crystal properties of a homologous series of a new class of alkoxyphenacylpyridine ligands and their copper( 11) complexes are reported. According to textural observations and calorimetric data, ligands with n = m>8 and copper complexes with n = m26, where n, m denote the number of carbon atoms in the alkoxy chains, exhibit liquid crystal properties. The mesogenic ligands display monotropic nematic phases, while the mesogenic copper(l1) complexes give enantiotropic smectic A phases.
