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-.
提供了可以用作电子器件中半导体材料的芴-噻吩共聚物。芴-噻吩共聚物的化学式为I。在化学式I中,Ac是具有2到5个融合芳香环的芴基基团。芴基可以是未取代的或取代有来自烷基、烷氧基、硫代烷基、芳基、芳基烷基、卤素、卤素烷基、羟基烷基、杂原子烷基、烯基或其组合的取代基。二价基团Q从化学式III中选择,其中每个R1和R2基团独立地选择自氢、烷基、烷氧基、硫代烷基、芳基、芳基烷基、卤素、卤素烷基、羟基烷基、杂原子烷基、烯基或其组合。化学式I中的下标n是至少等于4的整数。化学式I中的星号表示与另一个基团的连接位置,例如化学式-Ac-Q-的另一个重复单元。
