MAGNETIC INVESTIGATIONS ON LIQUID-CRYSTALLINE METALLOPOLYMERS

In this contribution, magnetic investigations on materials, which esse ntially combine mesogenic and polymeric properties, were presented. In the glassy and the smectic phase of a copper(II) containing polymer w e observed remarkable antiferromagnetic exchange interactions between the copper centers, whereas in the isotropic phase, the magnetism foll owed the Curie-Weiss law. The monomeric model compound showed Curie-We iss behaviour. In addition, we describe the magnetic behaviour of meso genic compounds, resulting from the incorporation of rare-earth ions i n chelating units of the liquid-crystalline Schiff base polymer.
