Patent application numberDescriptionPublished
20100117035ELECTROCONDUCTIVE TIN OXIDE HAVING HIGH MOBILITY AND LOW ELECTRON CONCENTRATION - Tin oxide having high mobility and a low electron concentration, and methods for producing layers of the tin oxide layers on a substrate by atmospheric pressure chemical vapor deposition (APCVD) are disclosed. The tin oxide may undoped polycrystalline n-type tin oxide or it may be doped polycrystalline p-type tin oxide. When the layer of tin oxide is formed on a crystalline substrate, substantially crystalline tin oxide is formed. Dopant precursors for producing doped p-type tin oxide are also disclosed.05-13-2010

20120085992Furan Conjugated Polymers Useful for Photovoltaic Applications - The present invention provides for a polymer comprising a π-conjugated backbone comprising a furan. The polymer has a narrow or low band gap and/or is solution processable. In some embodiments, the polymer is PDPP2FT or PDPP3F. The present invention also provides for a device comprising the polymer, such as a light-emitting diode, thin-film transistor, chemical biosensor, non-emissive electrochromic, memory device, photovoltaic cells, or the like.04-12-2012

20110003967SOLUBLE ALTERNATING DONOR-ACCEPTOR CONJUGATED POLYMER ELECTROCHROMES - Embodiments of the invention are directed to alternating donor-acceptor (DA) polymers that are soluble and display a blue or green neutral state that oxidizes to a transmissive state for use as an electrochromic polymer. The D units have 3,4-dioxythiophene, 3,6-dialkoxythieno[3,2-b]thiophene or 3,5-dialkoxy-dithieno[3,2-b:2′,3′-d]thiophene groups. Embodiments of the invention are directed to a method for preparation of the alternating DA polymeric sequences of the DA polymers by a cross-condensation of a nucleophilic acceptor monomer and an electrophilic donor monomer.01-06-2011
20110046330BLACK SOLUBLE CONJUGATED POLYMERS WITH HIGHLY TRANSMISSIVE OXIDIZED STATE - A soluble donor-acceptor electrochromic polymer (DA-ECP) is prepared that absorbs light throughout at least the majority of the visible range and is essentially black to the human eye when in the neutral state, but is highly transmissive when electrochemically doped. The conjugated polymer has acceptor units separated by sequences of a plurality of donor units. The sequences can be monodispersed or polydispersed. The DA-ECP is prepared by the polycondensation of a plurality of at least one donor-acceptor oligomer (DA-oligomer) that has at least one internal acceptor repeating unit and at least one donor repeating unit on all termini of the oligomer, and optionally, a plurality of at least one donor monomer and/or donor oligomer.02-24-2011
20110251370BLACK SOLUBLE CONJUGATED POLYMERS WITH HIGH CHARGE CARRIER MOBILITIES - A soluble fused donor-acceptor conjugated polymer (fDA-CP) is prepared that absorbs light throughout nearly all the visible spectrum and is essentially black to the human eye when in the neutral state. The conjugated polymer has acceptor units that are isolated by a plurality of fused donor units. The fDA-CP assumes a conformation that results in a close π-stacking between adjacent lamella with a separation of less than 4.5 Å in the solid state and extended conjugation to promote high charge carrier mobilities. The fDA-CP is prepared by the polycondensation of a plurality of at least one fused donor-acceptor oligomer (fDA-oligomer) that has a flat internal acceptor unit and at least one fused donor unit incorporated in the oligomers, and optionally, an additional conjugated aromatic monomer or oligomer copolymerized with the fDA-oligomers.10-13-2011

20100298527GREEN TO TRANSMISSIVE SOLUBLE ELECTROCHROMIC POLYMERS - Green to transmissive soluble electrochromic polymers are conjugated polymers having a plurality of repeating units where repeating units are a plurality of substituted dioxyheterocycle based donor groups coupled to an acceptor group. The conjugated polymer absorbs radiation within a first band of the visible spectrum and a second band of the visible spectrum when in a neutral state resulting in a green color and is transmissive when in an oxidized state. The polymers are soluble allowing processing of films and coatings from solution.11-25-2010

20120032104PROCESSING METHOD FOR WATER SOLUBLE POLYMERIC MATERIALS - Embodiments of the invention are directed to a method of forming a film of an insoluble conjugated polymer (CP) by deposition of an ionic CP from aqueous solution and converting the ionic CP to the insoluble CP. The ionic CP can be the salt of a carboxylic acid, sulfonic acid, phosphonic acid, boronic acid, amine, imine, phosphine, thioether, or complexed bidentate or polydentate ligand. The insoluble CP film can be used with an aqueous electrolyte solution for use as: an electrochromic film; charge injection layer for a solar cell, LED, and FET; conventional paints; supercapacitor; battery; electronic paper; anti-static coating; transparent conductor; sensors; anti-microbial coating; adhesive; RFID; or memory system.02-09-2012

20120067395EARTH-TONED PHOTOVOLTAIC DEVICES - The invention is directed to an assembly of photovoltaic cells having at least two different earth-toned colors, where different colors are situated in different cells, the cells color being defined by the donor-acceptor (DA) π-conjugated polymer and an acceptor moiety combination comprising the photoactive layer of the cell, and where the different colored solar cells are coupled into an assembly. The assembly can be flexible and can have colors specifically arranged in a camouflage or other pattern.03-22-2012
