  • Polythiophenes (PT)

    Polythiophenes result from the polymerization of thiophenes, a sulfur heterocycle, that can become conducting when electrons are added or removed from the conjugated pi-orbitals via doping. A number of applications have been proposed for conductin…

  • Oligomer

    In chemistry, an oligomer consists of a limited number of monomer units, in contrast to a polymer which, at least in principle, consists of an unbounded number of monomers. Many oils are oligomeric, such as liquid paraffin. Plasticizers are oligomeri…
