专利号:US-6603070-B2 优先权日:2000-07-21 标题 :Convergent synthesis of multiporphyrin light-harvesting rods 发明人:LINDSEY JONATHAN S; LOEWE ROBERT S 权利人:UNIV NORTH CAROLINA STATE 摘要:The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A 1 (A b+1 ) b , wherein b is at least 1, A 1 through A b+1 are covalently coupled rod segments, and each rod segment A 1 through A 1+b comprises a compound of the formula X 1 (X m+1 ) m wherein m is at least 1 and X 1 through X m+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.

专利号:US-9957622-B2 优先权日:2009-07-23 标 题 :Device and method of obtaining diols and other chemicals using decarboxylation 发明人:MOSBY JAMES; BHAVARAJU SAI; KARANJIKAR MUKUND 权利人:FIELD UPGRADING LTD 摘要:A method for converting carboxylic acids (including carboxylic acids derived from biomass) into hydrocarbons. The produced hydrocarbons will generally have at least two oxygen containing substituents (or other substituents). In one example of application, the electrolysis converts alkali salts of carboxylic acids into diols which can then be used as solvents or be dehydrated to produce dienes, which can then be used to produce elastic polymeric materials. This process allows custom synthesis of high value chemicals from renewable feed stocks such as carboxylic acids derived from biomass.

专利号:US-4402804-A 优先权日:1982-05-17 标题 :Electrolytic synthesis of aryl alcohols, aryl aldehydes, and aryl acids 发明人:JACKSON PATRICIA J 权利人:PPG INDUSTRIES INC 摘要:Disclosed is a method of synthesizing compounds chosen from the group consisting of benzyl alcohol, benzaldehyde, benzoic acid, phenoxy benzyl alcohol, phenoxy benzaldehyde, phenoxy benzoic acid, and mixtures thereof by providing a composition of a current carrying component, such as a fluoroborate salt or a tetraethylammonium salt, a solvent, and a methyl aryl compound in contact with an anode and cathode. The solvent is reduced at the cathode and the methyl substituted aryl at the anode whereby to form product. According to an alternative exemplification of the invention, the anode and cathode are separated by a permionic membrane and a source of oxygen is provided in contact with the cathode and the permionic membrane.
专利号:US-8062756-B2 优先权日:2005-08-26 标题:Stepwise growth of oligomeric redox-active molecules on a surface without the use of protecting groups 发明人:BOCIAN DAVID F; LINDSEY JONATHAN S; JIAO JIEYING 权利人:BOCIAN DAVID F; LINDSEY JONATHAN S; JIAO JIEYING; REGENTS OFT THE UNIVERSITY OF CALIFORNIA; UNIV NORTH CAROLINA STATE 摘要:This invention provides a procedure for growing oligomers via a stepwise process. The oligomers can include porphyrins, which have been previously shown to be attractive candidates for molecular-based information storage. The stepwise synthesis procedure requires no protecting groups, thus eliminating protection/deprotection reactions that add complexity to the process.
