A copolymer of Formula I
- wherein
- Ac is a radical of an acene having 2 to 5 fused benzene rings, wherein Ac can be optionally substituted with a substituent selected from an alkyl, alkoxy, thioalkyl, aryl, aralkyl, halo, haloalkyl, hydroxyalkyl, heteroalkyl, alkenyl, or combinations thereof;
- Ra is each independently selected from hydrogen, alkyl, alkoxy, alkenyl, aryl, heteroaryl, aralkyl, heteroaralkyl, heteroalkyl, or hydroxyalkyl;
- Q is a divalent group of Formula II, III, IV, or V;
- R1 and R2 are each independently selected from hydrogen, alkyl, alkoxy, thioalkyl, aryl, aralkyl, halo, haloalkyl, hydroxyalkyl, heteroalkyl, or alkenyl;
- and
- n is an integer greater than or equal to 4.
