    Notes: Macromolecular solids of highly aromatized structure can exhibit giant polarization. Their structures must be capable of providing long-range electron orbital delocalization. Intermolecular conformality of the orbitals of these huge molecules can result in ready carrier formation. The ready transport of these electronic holes and electronic carriers as polarons able to range over long molecular domains will then produce the giant polarization characteristic of the nomadic polarization mechanism. Recent developments in the synthesis and characterization of such materials new make available a new and interesting class of very stable organic dielectrics having dielectric constants in excess of 100. A number of such materials are described.

    A warning about structures of thiophene polymers (1984)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 22 (1984), S. 3789-3794

    Topics: Chemistry and Pharmacology
    Notes: 2,5-Dichlorothiophene, 2,5-dibromothiophene, and tetrabromothiophene have been polymerized with anhydrous sodium sulfide in N-methylpyrrolidone (NMP) at 250°C to insoluble products which contain structural fragments derived from both the starting thiophene and the NMP. The copolymers absorb 0.5 to 1.0 times their weights of iodine to give materials with electrical conductivities of about 10-5 (ohm cm)-1 at 16 kbar and 10-7 (ohm cm)-1 at atmospheric pressure.
