Acene-thiophene copolymers are provided that can be used as semiconductor materials in electronic devices. The acene-thiophene copolymers are of Formula I. In Formula I, Ac is a radical of an acene having 2 to 5 fused aromatic rings. The acene can be unsubstituted or substituted with a substituent selected from an alkyl, alkoxy, thioalkyl, aryl, aralkyl, halo, haloalkyl, hydroxyalkyl, heteroalkyl, alkenyl, or combinations thereof. Divalent group Q is selected from Formula III where each R1 and R2 group is independently selected from hydrogen, alkyl, alkoxy, thioalkyl, aryl, aralkyl, halo, haloalkyl, hydroxyalkyl, heteroalkyl, alkenyl, or combinations thereof. The subscript n in Formula I is an integer equal to at least 4. The asterisks in Formula I indicate the location of attachment to another group such as another repeat unit of formula--Ac-Q-.
