Conjugated polymers and dendrimers, process for their preparation and their use.

Abstract

The invention relates to conjugated polymers and to dendrimers comprising 9,10-dihydrophenanthrene structural units, to processes for their prepn. and to their use in electronic components, esp. in polymeric org. light-emitting diodes, to monomers for their prepn., and to components and light-emitting diodes comprising such polymers and dendrimers. These polymers and dendrimers exhibit improved color stability and lower operating voltage increase so that the life span of the polymer light-emitting diodes are longer. [on SciFinder(R)]
