  • Patent number: 7097757
    Abstract: A new class of polymers with a highly ordered state having unique electrical, electronic, optical, ferromagnetic, piezoelectric, ionic, or superconducting properties are achieved. The polymers are highly crystalline, exhibiting both long and short range order, and an associated nanoscale lattice parameter. The polymers are fabricated by forming a conductive set of nanoscale waveguides (composed of functional molecules and charge carriers, i.e., polarons, bipolarons, superpolarons, spins, ions, copper pair electrons) throughout a polymer lattice. These “molecular waveguides” are characterized by a width or diameter comparable to the size of the lattice cell.
