Polyphenylenes are macromolecules which comprise benzenoid aromatic nuclei directly joined to one another by C–C bonds. These materials have been known for many years. Until 1979, the major interest in polyphenylenes stemmed from their characteristic thermal and thermo-oxidative stabilities. More recent continuing interest ...
