Abstract
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.
