Copolymers Of Soluble Poly(Thiophenes) With Improved Electronic Performance
View pageUS Patent:
20060237695, Oct 26, 2006
Filed:
Mar 16, 2006
Appl. No.:
11/376550
Inventors:
Shawn Williams - Pittsburgh PA, US
Darin Laird - Pittsburgh PA, US
Caton Goodman - Pittsburgh PA, US

International Classification:
H01B 1/12
US Classification:
252500000
Abstract:
Polythiophene copolymers having tunable work functions and oxidation voltage onset. The ratio of monomer can be varied to achieve the desired property for a particular application. One monomer can be unsubstituted thiophene. The copolymer microstructure can be random. Another monomer can be a 3-substituted thiophene such as 3-alkyl or a heteroatom substituted substituent. Heterojunction polymer photovoltaic cells can be fabricated with excellent voltage onset properties compared to devices having corresponding homopolymers.

International Classification:
C08G 75/00
B05D 3/02
B05D 3/02
US Classification:
427372200, 528373000
Abstract:
Latent doping is provided wherein a conducting polymer is mixed with a dopant in solution without the doping reaction occurring unless solvent is removed. Regioregular polythiophenes are a particularly important embodiment. A composition comprising (i) at least one polymer comprising conjugation in the polymer backbone, (ii) at least one dopant for the polymer, (iii) at least one solvent for the polymer and latent dopant, wherein the polymer, the latent dopant, and the solvent are formulated so that the latent dopant does not substantially dope the polymer when formulated, but does substantially react with the polymer when the solvent is removed. Formulation of the composition can comprise adjusting the order of mixing, the amounts of the components, and the temperature. Methods of formulating the compositions and methods of using the compositions are also provided. OLED, PLED, photovoltaic, and other organic electronic devices can be fabricated.
Solvent System For Conjugated Polymers
View pageUS Patent:
20080299293, Dec 4, 2008
Filed:

International Classification:
C08F 28/06
C08K 3/04
B05D 5/12
C08K 3/04
B05D 5/12
US Classification:
427 58, 526256, 524495
Abstract:
A solvent system for a conjugated polymer that includes at least two different solvents, at least one first solvent and at least one second solvent wherein the second solvent comprises a heterocyclic ring to improve the characteristics of materials made therefrom. Use of the solvent system to improve the electronic and/or optoelectronic characteristics of materials that include conjugated polymers, such as polythiophenes, optionally including n-acceptors, which are cast from a composition that includes the solvent system. In some embodiments the improved characteristics include higher absorption of solar radiation, increased current densities and higher power conversion efficiencies. As a result, materials made with the present solvent systems are well-suited for use in a variety of electronic devices including, photovoltaic cells, light emitting diodes, and transistors.
