Synthesis of new metallomesogens containing a metal 4-substituted-piperazine-1 -dithiocarboxylate core

New metallomesogens, bis[4-(n-alkyl)- and bis[4-(4-n-alkoxyphenyl)-piperazine-1-dithiocarboxylato]metal(II) complexes, have been synthesized and shown to exhibit either a nematic or a smectic phase.
