1B08 Mesomorphic Properties of 5-Substituted Bis (tropolonato) metal Complexes

Abstract

The mesomorphic properties of bis (tropolonato) metal complexes will be discussed. The copper and oxyvanadium complexes with two ester groups at the C-5 position showed the highly ordered smectic phases from the X-ray diffraction study and microscopic observations. The textures were similar to those of bis (5-alkoxytropolonato) metal complexes, which have been assigned to be smectic C, smectic B_<hex>, and smectic G phases.
