Synthesis and Mesomorphic Properties of Palladium(Ⅱ) Complexes Based on 3,4,5-Trialkoxy Benzonitrile Ligands
Myongsoo Lee*, Yong-Sik Yoo, Moon-Gun Choi
The synthesis and characterization of the nitrile ligands 3,4,5-tridodecyloxy benzonitrile (7) and 3,4,5-trioctadecyloxy benzonitrile (8), and their corresponding palladium(Ⅱ) complexes are described. The nitrile ligands display only a crystalline phase and do not show liquid crystalline behavior, while their corresponding palladium(Ⅱ) complexes dispaly an enantiotropic columnar mesophase. The induction of the columnar mesophase is mainly due to dimerization through the palladium complexation of the half disk-like nitrile ligands giving rise to a trans square planar geometry.
