Triarylamine containing polymers and electronic devices

Abstract

A conjugated or partially conjugated polymer including a structural unit of Formula I in the backbone: where Ar 1 and Ar 2 are each independently a substituted or unsubstituted arylene or hetero arylene group with two or more aromatic rings fused together and Ar 3 is an aryl or heteroaryl group of C 4 to C 40 or substituted aryl or heteroaryl group of C 4 to C 40 and devices containing such polymer. In addition, a composition of Formula V wherein Ar 1 and Ar 2 are arylene or heteroarylene groups and Ar 3 is an aryl or heteroaryl group and wherein X is a leaving group such as halogen, boronic acid or boronate ester.

         2 . The composition of  claim 1 , wherein X is a halogen, boronic acid or boronate ester. 
     
     
         3 . The composition of  claim 2 , wherein X is bromine. 
     
     
         4 . The composition of  claim 1 , Ar 1  and Ar 2  are each independently a substituted or unsubstituted arylene or heteroarylene group with two or more aromatic rings fused together. 
     
     
         5 . The composition of  claim 4 , wherein Ar 1  and Ar 2  are a substituted or unsubstituted naphthalenediyl, anthracenediyl or fluorenediyl. 
     
     
         6 . The composition of  claim 5 , wherein Ar 1  and Ar 2  comprise a fluorene having the Formula II 
       
         
           
           
               
               
           
         
         where Q is R 1  or Ar, wherein Ar is a aryl or heteroaryl group of C 4  to C 40  or substituted aryl or heteroaryl group of C 4  to C 40 ; R 1  is independently, in each occurrence H, C 1-40  hydrocarbyl or C 3-40  hydrocarbyl containing one or more S, N, O, P or Si atoms, or both of R 1  together with the 9-carbon on the fluorene may form a C 5-20  ring structure that may contain one or more S, N, Si, P or O atoms; R 2  is independently in each occurrence a C 1 -C 40  hydrocarbon, C 3 -C 40  hydrocarbyl containing one or more heteroatoms of S, N, O, P or Si, or a substituted or unsubstituted aryl group or heteroaryl group; n is independently in each occurrence, 0-3. 
       
     
     
         7 . The composition of  claim 6 , wherein Ar 3  is an aryl or heteroaryl group of C 4  to C 40  or a substituted aryl or heteroaryl group of C 4  to C 40 . 
     
     
         8 . The composition of  claim 7 , wherein Ar 3  is a aryl or heteroaryl group having Formula III
