Patent ID: 8809839

Claim:
An organic semiconductor polymer represented by following Chemical Formula (1): wherein, in the Chemical Formula (1), G 1 and G 2 are the same or different and are independently selected from the group consisting of —O—, —S—, —Se—, and —CR 9 ═N—, where R 9 is one selected from the group consisting of hydrogen, a fluoro, a C1 to C30 linear or branched alkyl, a C3 to C30 cycloalkyl, a C1 to C20 partially fluorinated fluoroalkyl, a C1 to C20 perfluoroalkyl (C n F 2n+1 ), a C1 to C30 linear or branched alkoxy, a C3 to C30 cycloalkoxy, a C2 to C30 linear or branched alkoxyalkyl, a C4 to C30 cycloalkoxyalkyl and combinations thereof, R 1 and R 2 are the same or different and are independently selected from the group consisting of hydrogen, a fluoro, a C1 to C30 linear or branched alkyl, a C3 to C30 cycloalkyl, a C1 to C20 partially fluorinated fluoroalkyl, a C1 to C20 perfluoroalkyl (C n F 2n+1 ), a C1 to C30 linear or branched alkoxy, a C3 to C30 cycloalkoxy, a C2 to C30 linear or branched alkoxyalkyl, a C4 to C30 cycloalkoxyalkyl and combinations thereof, Ar is a substituted or unsubstituted C6 to C30 aromatic ring, or a substituted or unsubstituted C6 to C30 condensed polycycle, n is a polymerization degree and an integer of 8 or more, and a and b are independently integers ranging from 1 to 3, provided that if G 1 and G 2 are —O—, —S—, or —Se—, then at least one of R 1 and R 2 is a fluoro or a C1 to C20 perfluoroalkyl, and provided that if G 1 and G 2 are —CR 9 ═N—, at least one of R 1 , R 2 and R 9 is a fluoro or a C1 to C20 perfluoroalkyl.
