A conjugated or partially conjugated polymer including a structural unit of Formula I in the backbone: (Formula I), where Arl and Are are each independently a substituted or unsubstituted arylene or hetero arylene group with two or more aromatic rings fused together and Ar3 is an aryl or heteroaryl group of C4 to C40 or substituted aryl or heteroaryl group of C4 to C40 and devices containing such polymer. In addition, a composition of: (Formula V), wherein Arl and Are are arylene or heteroarylene groups and Ar3 is an aryl or heteroaryl group and wherein X is a leaving group such as halogen, boronic acid or boronate ester. |
