Polymers for use in organic electroluminescent devices

Abstract

A polymer comprising an optionally substituted first repeat unit of formula (1): wherein F is a divalent residue; each G in each occurrence is independently a divalent residue; r is at least 1; each p is independently 0 or 1 and each corresponding q is the other of 0 or 1; and G comprises a heteroatom in the case where n is 1.

1 - 28 . (canceled) 
   
   
       29 . An optionally substituted compound of formula (2); 
     
       
         
         
             
             
         
       
       wherein 
       G is, independently on each occurrence, a divalent residue; 
       r is at least 1; 
       p and q
 are 0 or 1, wherein when p is 0, q is 1 and when p is 1, q is 0; and 
 
       P is, independently on each occurrence, a polymerizable group; 
       wherein when r is 1, G comprises a heteroatom. 
     
   
   
       30 . The optionally substituted compound of  claim 29 , wherein r is at least 2. 
   
   
       31 . The optionally substituted compound of  claim 29 , wherein G is, independently on each occurrence, selected from the group consisting of CR 2 , NR, PR, POR, BR, O, S, SO, SO 2 , and SiR 2 , wherein each R is, independently, H or a substituent. 
   
   
       32 . The optionally substituted compound of  claim 29 , wherein r is 1 and G is, independently on each occurrence, selected from the group consisting of NR, PR, POR, BR, O, S, SO, SO 2 , and SiR 2 . 
   
   
       33 . The optionally substituted compound of  claim 29 , wherein r is greater than 1 and G is, independently on each occurrence, selected from the group consisting of CR 2 , NR, PR, POR, BR, O, S, SO, SO 2 , and SiR 2 . 
   
   
       34 . The optionally substituted compound of  claim 29 , wherein R is, independently on each occurrence, selected from the group consisting of H, C 1  to C 40  alkyl, alkoxy, aryl, aryloxy, heteroaryl, and heteroaryloxy. 
   
   
       35 . The optionally substituted compound of  claim 29 , wherein at least one G is CR 2  or SiR 2 , wherein said R groups are linked to form a ring. 
   
   
       36 . The optionally substituted compound of  claim 29 , wherein P is, independently on each occurrence, a polymerizable group selected from the group consisting of boronic acid groups, boronic ester groups, borane groups, reactive halide groups, and groups of formula —O—SO 2 -Z, wherein Z is selected from the group consisting of optionally substituted alkyl and optionally substituted aryl.
