专利号:US-8192590-B1 优先权日:2008-04-14 标 题:Microwave-assisted formation of sulfonium photoacid generators 发明人:BELFIELD KEVIN D; YANEZ CICERON O 权利人:BELFIELD KEVIN D; YANEZ CICERON O; UNIV CENTRAL FLORIDA RES FOUND 摘要:Efficient method for preparing sulfonium photoacid generators (PAGs) by microwave-assisted reaction of diarylsufides in the presence of alkylaryliodonium salts. Microwave-assisted synthesis of the PAGs is significantly faster, reducing reaction time with less energy consumption. Reaction times using the microwave-assisted synthesis are in a range of from 90 to 420 faster than conventional thermal conditions. The photoacid quantum yields of several salts prepared by the microwave reaction were measured; the photoacid quantum yields of new sulfonium PAGs were in a range from 0.01 to 0.4 times greater than yields from conventional synthesis. Incorporating a nitro group in the structures of the sulfonium salts increased photoacid quantum yield, induced intersystem crossing and increased the efficiency of photoacid generation compounds.

专利号:US-6469193-B1 优先权日:1999-02-26 标 题 :Efficient synthesis of alkyl carbonates 发明人:JUNG KYUNG WOON 权利人:UNIV SOUTH FLORIDA 摘要:Efficient synthetic methods towards mixed aliphatic carbonates through the three component couplings of aliphatic alcohols, alkyl halides and carbon dioxide in the presence of cesium carbonate and tetrabutylammonium iode (TBAI). Due to their enhanced nucleophilicities, cesium alkoxides are smoothly incorporated into CO 2 , allowing for mild reaction conditions such as ambient temperatures and short reaction durations. Various primary and secondary substrates are compatible under the standard conditions, offering high yields, while chiral templates such as α-hydroxy carbonyls are resistant to racemization.
专利号:WO-2009126118-A1 优先权日:2008-04-10 标题:Unique processable green polymer with a transmissive oxidized state for realization of commerical rgb based electrochromic device applications 发明人:TOPPARE LEVENT KAMIL; GUNBAS GORKEM EMRULLAH; DURMUS ASUMAN 权利人:TOPPARE LEVENT KAMIL; GUNBAS GORKEM EMRULLAH; DURMUS ASUMAN 摘要:In the present invention a method for synthesis of neutral state green polymer PDOPEQ) is developed. The method developed in this invention is characterized by; a) obtaining 2,3-bis(3,4-bis(decyloxy)phenyl)-5,8-dibromoquinoxaline, b) b) obtaining tributyl (2,3-dihydrothieno[3,4-b][l,4]dioxin-5-yl)stannane c) c) Using coupling to attach donor EDOT moieties to the acceptor quinoxaline unit to give the title compound (DOPEQ) in satisfactory yields; d) obtaining neutral state green polymer (PDOPEQ) by using either electrochemical or chemical methods. The polymers synthesized up to date mainly absorb/reflect blue and red colors in the reduced state. Conversely, to obtain a green colored polymer in the reduced state, one should have two absorption bands centered at the blue and red regions of the visible spectrum and moreover, these absorption bands should be manipulated in the same manner at applied potentials.
专利号:US-8975427-B2 优先权日:2010-04-28 标题 :Synthesis of alkyl cyclopentadiene compounds 发明人:HARLAN C JEFF; CAO XIANYI; RIX FRANCIS C 权利人:HARLAN C JEFF; CAO XIANYI; RIX FRANCIS C; UNIVATION TECH LLC 摘要:A method of synthesizing an alkyl cyclopentadiene compound is disclosed. The method includes contacting at least one cyclopentadienyl anion source and at least one alkyl group source to form at least one alkyl cyclopentadiene compound. The method further includes extracting the alkyl cyclopentadiene compound with a hydrocarbon solvent. The alkyl cyclopentadiene compound may be converted to a metallocene catalyst compound.
