Publication number: 20030027970Abstract: The organic polymers of the invention have electrical semiconductor properties. The compounds have a backbone of phenylene groups to which side groups with semiconductor properties, or which impart semiconductor properties to the polymer, are bonded. The polymers are obtained by Bergmann cyclization from compounds that contain aromatic groups to which vicinal ethynyl groups are bonded. The polymers are suitable for the production of semiconductor components, such as organic transistors or diodes.Type: ApplicationFiled: July 1, 2002Publication date: February 6, 2003Inventors: Roland Haasmann, Marcus Halik, Gunter Schmid, Andreas Walter

Publication number: 20020161174Abstract: Provided is an aromatic polymer phosphonic acid derivative in which a phosphonic acid derivative group is directly bound to aromatic ring. Said aromatic polymer phosphonic acid derivative can be produced by brominating a specific aromatic polymer compound with a brominating agent, then acting thereon trialky1 phosphite in the presence of a nickel halide catalyst to give a phosphonic acid di-ester, and further, by hydrolyzing the di-ester. The aromatic polymer phosphonic acid derivative is excellent in radical resistance and used for a solid polymer type fuel cell.Type: ApplicationFiled: February 5, 2002Publication date: October 31, 2002Applicant: SUMITOMO CHEMICAL COMPANY, LIMITEDInventors: Shigeru Sasaki, Arihiro Yashiro, Yasuaki Hidaka
