New Liquid Crystalline Compounds Containing Transition Metals

Abstract
A survey on the syntheses and mesomorphic properties of some organometallic or coordination transition metal complexes is reported. In particular, this review is dealing with palladium (II) complexed with three different classes of azobenzene ligands namely p-alkoxy(or p-alkyl) p'-ester azobenzenes, p-alkoxy-p'-alkylazobenzenes and p-alkoxy-phenil azo benzenes. A preliminar account on the synthesis, characterization and structural properties of a series of smectic copper (II). Schiff bases coordination compounds, together with a simple molecular model, is also presented.
