20090032811 | FUNCTIONALIZATION OF POLY(ARYLENE-VINYLENE) POLYMERS FOR ELECTRONIC DEVICES - A method is provided for modifying a poly(arylene vinylene) or poly(heteroarylene vinylene) precursor polymer having dithiocarbamate moieties by reacting it with an acid and further optionally reacting the acid-modified polymer with a nucleophillic agent. Also provided are novel polymers and copolymers bearing nucleophillic side groups which are useful as components of electronic devices, e.g. in the form of thin layers. | 02-05-2009 |

Also provided are novel polymers and copolymers bearing nucleophilic side groups which are useful as components of electronic devices, e.g. in the form of thin layers. | 02-05-2009 |
20090183767 | METHOD OF PREPARING DERIVATIVES OF POLYARYLENE VINYLENE AND METHOD OF PREPARING AN ELECTRONIC DEVICE INCLUDING SAME - A technique is described for the preparation of polymers according to a process in which the starting compound of formula (I) is polymerized in the presence of a base in an organic solvent. No end chain controlling agents are required during the polymerisation to obtain soluble precursor polymers. The precursor polymer such obtained comprises structural units of the formula (II). In a next step, the precursor polymer (II) is subjected to a conversion reaction towards a soluble or insoluble conjugated polymer by thermal treatment. The arylene or heteroarylene polymer comprises structural units of the formula III. In this process the dithiocarbamate group acts as a leaving group and permits the formation of a precursor polymer of structural formula (II), which has an average molecular weight from 5000 to 1000000 Dalton and is soluble in common organic solvents. The precursor polymer with structural units of formula (II) is thermally converted to the conjugated polymer with structural formula (III). | 07-23-2009 |
20090246532 | POLYIPTYCENYLENE VINYLENE AND METHOD OF MAKING THE SAME - Methods are provided for obtaining soluble or insoluble poly(iptycenylene vinylene) homo- and co-polymers via a soluble precursor polymer. The polymers obtained by the methods can be used in electronic or opto-electronic devices, e.g., chemosensors. | 10-01-2009 |
