Pyrene-based Polymers for Organic Light Emitting Diodes (oleds )
The present invention relates to novel pyrene-based polymers, methods of preparing the same and uses thereof, in particular for electroluminescent devices. The novel polymers of the invention have the following general formula (I): wherein R1, R2, R3, R4, R5, R6, R7 and R8 are independently of each other hydrogen, halogen, in particular F, SiR100R101R102, or an organic substituent, or R6 and R7, R3 and R4, and/or any of the substituents R1, R2, R3, R4, R5, R6, R7 and/or R8, which are adjacent to each other, together form an aromatic, or heteroaromatic ring, or ring system, which can optionally be substituted, n1 and n2 are 0, 1, or 2, R100, R101 and R102 are independently of each other C1-C18 alkyl, substituted or unsubstituted C6-C18 aryl, and Ar1 and Ar2 are each independently of each other a substituted or unsubstituted arylene or heteroarylene group.
