标 题 :Dipyrin based materials for photovoltaics, compounds capable of undergoing symmetry breaking intramolecular charge transfer in a polarizing medium and organic photovoltaic devices comprising the same

摘要:The present disclosure generally relates to organic photosensitive optoelectronic devices comprising at least one boron dipyrrin compound. In addition, the present disclosure relates to methods of making organic photosensitive optoelectronic devices comprising at least one boron dipyrrin compound. The present disclosure also generally relates to chromophoric compounds that combine strong absorption of light at visible wavelengths with the ability to undergo symmetry-breaking intramolecular charge transfer (ICT), and their use for the generation of free carriers in organic photovoltaic cells (OPVs) and electric-field-stabilized geminate polaron pairs. The present disclosure also relates to the synthesis of such compounds, methods of manufacture, and applications in photovoltaic systems and organic lasers.

权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:This disclosure provides for routes of synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, including catalytic methods. For example, there is provided a process for producing an α,β-unsaturated carboxylic acid or a salt thereof, the process comprising: (1) contacting in any order, a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a metal-treated chemically-modified solid oxide such as a sulfur oxoacid anion-modified solid oxide, a phosphorus oxoacid anion-modified solid oxide, or a halide ion-modified solid oxide, to provide a reaction mixture; and (2) applying reaction conditions to the reaction mixture suitable to produce the α,β-unsaturated carboxylic acid or the salt thereof. Methods of regenerating the metal-treated chemically-modified solid oxide are described.

摘要:Catalysts and catalytic processes for the synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, which are carried out in a diluent or in the absence of a diluent. In an aspect, ethylene and CO2 can be contacted with a Group 8-11 transition metal precursor compound or a Group 8-11 transition metal metalalactone compound in the presence of a metal-treated chemically-modified solid oxide (MT-CMSO) or a metal-treated solid oxide (MT-SO), to form a metal acrylate. As the catalytic activity wanes in either the presence or absence of a diluent, pressure cycling—that is, pressurizing the reaction system with CO2 and an olefin such as ethylene for a time period, releasing the pressure, then re-pressurizing with CO2 and ethylene—can rejuvenate the catalyst and restore its declining catalytic activity.

标 题:Polyalphaolefins made from dimer olefins obtained from branched c10 monoolefins using solid acid catalyst
发明人：MALINSKI THOMAS; GEE JEFFREY C; BISCHOF STEVEN M; KERNS SPENCER A; HILLIER JAMES; WEBSTER-GARDINER MICHAEL S
权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:Synthesis of polyalphaolefins by oligomerization of one or more branched C 10 monoolefins with a solid acid catalyst to form an oligomer product, followed by hydrogenation of a C 20+ olefin portion of the oligomer product to form the polyalphaolefins. The solid acid catalyst is selective to C 20 olefin dimers.
