    摘要: 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.

    摘要: A composition comprising a homopolymer or a copolymer comprising bithiophene units for use in, for example, low band gap materials including uses in organic photovoltaic active layers. The band gap and other properties can be engineered by polymerization methods including selection of monomer structure and ratio of monomer components. In addition, a dimer adapted for making alternating copolymers further comprising one first monomer moiety comprising at least one bithiophene moiety compound covalently linked to one second monomer moiety comprising a different bithiophene moiety or at least one moiety that is not a bithiophene. The composition can be copolymerized to form an alternating copolymer that can be further processed to form a polymeric film used in a printed organic electronic device. A series of novel copolymers are designed that would allow fabrication of materials with tailor made electronic and/or mechanical properties that can be easily manipulated through molecules chemical structure and potentially result in long term stability under ambient conditions that can be advantageous for use in organic electronics (e.g., OPVs, OLEDs, OFETs). Improved methods are disclosed for making monomers comprising a benzo[2,1-b:3,4-b′]dithiophene moiety that are useful as electronics materials.

    摘要: Regioregular poly(3-alkylthiophenes) and other polythiophenes can be prepared by living polymerization which have good solubility, processability and environmental stability. The polymerization method can afford regioregular poly(3-alkylthiophenes) in high yields. Kinetic study of polymerization revealed the living character of this process. The molecular weight of poly(3-alkylthiophenes) is a function of the molar ratio of the monomer to nickel initiator, and conducting polymers with relatively narrow molecular weight distribution (PDI
