| 20120088900 | PROCESS FOR PREPARING REGIOREGULAR POLY-(3-SUBSTITUTED) THIOPHENES, SELENOPHENES, THIAZOLES AND SELENAZOLES - A process for preparing a regioregular homopolymer or copolymer of 3-substituted thiophene, 3-substituted selenophene, 3-substituted thiazol or 3-substituted selenazol by a) reacting a 3-substituted 2,5-dihalothiophene, 2,5-dihaloselenophene, 2,5-dihalothiazol or 2,5-dihaloselenazol with reactive zinc, magnesium and/or an organomagnesium halide to give an organozinc or organomagnesium intermediate containing one halozinc or one halomagnesium group, b) bringing the organozinc or the organomagnesium intermediate into contact with a Ni(II), Ni(O), Pd(II) or Pd(O) catalyst to initiate the polymerization reaction, and c) polymerizing the organozinc or the organomagnesium intermediate to give a regioregular head-to-tail homopolymer or copolymer of 3-substituted thiophene, 3-substituted selenophene, 3-substituted thiazol or 3-substituted selenazol characterized in that the polymerization reaction is carried out at a temperature rising from a lower temperature T | 04-12-2012 |
| 20110136973 | POLYBENZOTHIOPHENE POLYMERS AND PROCESS FOR THEIR PREPARATION - A polymer comprising the group of the formula (I) in particular derivatives of Poly[benzothiophen-2.6-diyl]. | 06-09-2011 |
| 20100234478 | PROCESS FOR PREPARATION OF CONDUCTING POLYMERS - Methods of preparing conducting polymers and the conductive polymers prepared therefrom are provided. The method includes a) combining a monomer-metal complex together with a manganese (II) halide to provide a monomer-manganese complex, and b) combining the monomer-manganese complex together with a metal catalyst to provide the conductive polymer. Electronic devices can be made using the polymers prepared as described herein. | 09-16-2010 |
| 20100206613 | PROCESS FOR PREPARATION OF CONDUCTING POLYMERS - Methods of preparing conducting polymers and the conductive polymers prepared therefrom are provided. Electronic devices can be made using the polymers prepared as described herein. A method of preparing a conducting polymer is disclosed comprising: combining a di(C | 08-19-2010 |
| 20100004423 | PROCESS FOR PREPARATION OF REGIOREGULAR POLY(3-SUBSTITUTED-THIOPHENE) - The invention provides a method of preparing regioregular HT poly(3-substituted-thiophene). The method includes contacting a 3-substituted-thiophene-metal complex with a manganese(II) halide to provide a 3-substituted-thiophene-manganese complex; and contacting the thiophene-manganese complex with a nickel(II) catalyst to provide the regioregular HT poly(3-substituted-thiophene). The substitution at the 3-position can be a variety of different groups. Additionally, unsubstituted and 3,4-disubstituted polythiophenes can also be prepared by the method. Electronic devices can be made using the polymers prepared as described herein. | 01-07-2010 |
| 20090253893 | PROCESS FOR SUBSTITUTED POLYTHIOPHENE POLYMERS - An improved process for preparing regioregular substituted polythiophenes is described where a substituted thiophene having at least two leaving groups is treated with an organomagnesium halide followed by zinc chloride or bromide and the resulting reaction mixture in solution is polymerized with a Ni(II) catalyst. | 10-08-2009 |
