Method for making unsymmetrically substituted fluorenyl compounds for nonlinear optical applications
Patent number: 6379590Abstract: A new method for producing unsymmetrically substituted fluorenyl compounds, one step of which is the preparation of 2,7-disubstituted fluoren-9-one derivatives via the nucleophilic substitution of a compound of the formula D wherein A′ is selected from the group consisting of —Br, —Cl, —F, —NO2, and —CN; A is selected from the group consisting of —NO2, —CN, —CO2R, —C(O)R, —SO2R, —SO2RF, —C(CN)═C(CN)2 and —CH═C(CN)2; RF is —CpF2p+1, p=from about 0 to about 10; R is an straight, branched or cyclic aliphatic alkyl group having about 1 to 10 carbon atoms, or an aromatic group such as phenyl or naphthyl; and is a carbonyl or a protected carbonyl such as a ketal or thio-ketal such as wherein R′ is —CrH2r+1; R″ is —(CH2)r—; and r is independently 2 or 3, with a nucleophilic reagent in the presence of an aprotic solventType: GrantFiled: December 2, 1994Date of Patent: April 30, 2002Assignee: AlliedSignal Inc.Inventors: Chengjiu Wu, Jianhui Shan -
Patent number: 6368769Abstract: Novel aromatic sulfonium compounds of general formula (I), photoacid generators comprising the same, and photopolymerizable compositions containing the same, capable of providing stereolithographic resin compositions which do not suffer from the hindrance to curing by oxygen, can easily give shaped articles having desired sizes by virtue of the high accuracy thereof in curing, and can attain a satisfactory curing depth owing to the high sensitivity thereof for radiant energy; and a stereolithographic process.Type: GrantFiled: July 6, 2000Date of Patent: April 9, 2002Assignee: Asahi Denki Kogyo Kabushiki KaishaInventors: Kazuo Ohkawa, Hiroyuki Tachikawa, Satoyuki Chikaoka
