| abstract |
A partly conjugated polymer contains repetitive units of formula (I) in which A is the same or different with zero to eight identical or different arylene and/or heteroarylene and/or vinylene and/or acetylene groups which, like the spiro-bifluorene structure, may be substituted. Polymers with repetitive units of formula (I) are suitable, for example, as electroluminescent materials. They are distinguished by high emission colour uniformity, good film-forming properties and high solubility. |
