Conducting and Magnetic Polymers

Abstract

Unsaturated polymeric materials with interesting electronic, optical and magnetic properties are being prepared. The major route to these materials is through the Ring Opening Polymerization (ROMP) of highly unsaturated monomers. The ROMP of substituted cyclooctatetraene and methylenecyclobutenes has been the major route to such materials. Materials with tailored electronic and physical properties have resulted from these studies. A recent development has been the synthesis of a precursor polymer for a potential organic ferromagnetic. Progress has been made in a number of different areas of synthesis of conjugated polymers. Particular emphasis has been placed on determining the conformation of polyacetylenes in solution and the factors that control solubility and conjugation length. The most subtle probe used was a chiral side group that produces a chiral conjugated backbone. The cis to trans isomerization of soluble plyacetylenes has been investigated in detail and the activation energies for the process has been accurately determined.
