Significance

High molecular weight poly(p-phenylene ethynylene)s (PPEs) with enhanced mechanical properties are generated by the metal-induced supramolecular polymerization of PPE polymers end-capped with 2,6-bis(1′-methylbenzimidazolyl)pyridine. Introduction of Fe(ClO4)2 or Zn(ClO4)2 produced a spontaneous increase in solution viscosity and led to mechanically robust spin-coated and solution-cast films as well as fibers.
