| abstract |
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 R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are independently of each other hydrogen, halogen, in particular F, SiR 100 R 101 R 102 , or an organic substituent, or R 6 and R 7 , R 3 and R 4 , and/or any of the substituents R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and/or R 8 , which are adjacent to each other, together form an aromatic, or heteroaromatic ring, or ring system, which can optionally be substituted, n 1 and n 2 are 0, 1, or 2, R 100 , R 101 and R 102 are independently of each other C 1 -C 18 alkyl, substituted or unsubstituted C 6 -C 18 aryl, and Ar 1 and Ar 2 are each independently of each other a substituted or unsubstituted arylene or heteroarylene group. |
