Abstract
The present invention relates to polymers with an extended system of conjugated double bonds constructed as homo and/or heterocyclic rings which are interlinked in pairs so that one ring is joined to the neighboring one at two adjacent atoms in the ring, in which one of these connections is made by a chemical bond to a ring atom of the neighboring ring and the other via a carbon, nitrogen, oxygen or sulphur atom to an atom of the neighboring ring adjacent said ring atom, their production and use in electrical, electronic and opto-electronic components.
