  • Patent number: 8227566
    Abstract: The present invention relates to polythiophenes, particularly regioregular head-to-tail poly(3-alkylthiophenes) (HT-PATs), block copolymers made therefrom, and their methods of formation. The present invention provides HT-PATs with well-defined, specific end-groups, functionalization of the defined HT-PATs, and incorporation of end group functionalized HT-PATs into block copolymers with structural polymers. The intrinsically conductive diblock and triblock copolymers, formed from the HT-PATs, have excellent conductivity and low polydispersities that are useful in a number of applications. The block copolymers of the present invention have been found to exhibit conductivities that range from a low of 10?8 S/cm for certain applications to as high as several hundred S/cm or more.

  • Patent number: 8211996
    Abstract: A method for the synthesis of well-defined rod-coil block copolymers consisting of P3HT donor and C60 acceptor chromophores (P3HT-b-P(SxAy)-C60) in a molecular architecture is reported for use in bulk-heterojunction (BHJ) solar cells. In thin films of the resulting block copolymer, reproducible self-assembly into well-defined “nanofibrils” is observed. This is the first example of a block copolymer containing a C60 derivative that shows exclusively a nanofibrilar structure. A substantial improvement in device performance is achieved when the block copolymer is used as a “surfactant” for controlling the interface morphology of the P3HT:PCBM donor-acceptor phase domains within the composite.

The oxidant solution includes an oxidizing agent, or oxidant, such as ferric chloride to oxidize the monomer, the oligomer, or both, and begin polymerization. By including an initiator in the form of the oligomer, which may have a lower oxidation potential than the monomer, the rate of polymerization is accelerated, resulting in the nanofibrous morphology. Therefore, the conducting polymer nanofibers may be synthesized without the use of surfactants, hard templates, or seeds, resulting in a simplified and accelerated polymerization process, which enhances homogenous nucleation of the conducting polymer nanofibers.
