Abstract
Official abstract text for this publication.
A polymer which has M n at least 4,000 and comprises polymerized units of a compound of formula NAr 1 A 2 A 3 , wherein Ar 1 , Ar 2 and Ar 3 independently are C 6 -C 40 aromatic substituents; Ar 1 , Ar 2 and Ar 3 collectively contain no more than one nitrogen atom and at least one of Ar 1 , Ar 2 and Ar 3 contains a vinyl group attached to an aromatic ring.
First claim
Opening claim text (preview).
1 . A polymer having M n at least 4,000 and comprising polymerized units of a compound of formula NAr 1 Ar 2 Ar 3 , wherein Ar 1 , Ar 2 and Ar 3 independently are C 6 -C 40 aromatic substituents; Ar 1 , Ar 2 and Ar 3 collectively contain no more than one nitrogen atom and at least one of Ar 1 , Ar 2 and Ar 3 contains a vinyl group attached to an aromatic ring. 2 . The polymer of claim 1 having M n from 6,000 to 1,000,000. 3 . The polymer of claim 2 in which the compound of formula NAr 1 Ar 2 Ar 3 contains a total of 4 to 12 aromatic rings. 4 . The polymer of claim 3 in which each of Ar 1 , Ar 2 and Ar 3 independently contains from 10 to 32 carbon atoms. 5 . The polymer of claim 4 in which Ar groups contain no heteroatoms other than nitrogen. 6 . The polymer of claim 5 in which only one vinyl group is present in the compound of formula NAr 1 Ar 2 Ar 3 . 7 . The polymer of claim 6 in which Ar groups consist of one or more of biphenylyl, fluorenyl, phenylenyl, carbazolyl and indolyl. 8 . An electronic device comprising one or more polymers of claim 1 . 9 . A light emitting device comprising one or more polymers of claim 1 .
