Claim:
An organic semiconductor compound comprising a structural unit represented by the following Chemical Formula 1: wherein, in Chemical Formula 1, R 1 is selected from one of hydrogen, a halogen (one of —F, —Cl, —Br, and —I), a substituted or unsubstituted linear or branched C 1 to C 30 alkyl group, a substituted or unsubstituted linear or branched C 2 to C 30 alkenyl group, a substituted or unsubstituted linear or branched C 2 to C 30 alkynyl group, a substituted or unsubstituted C 7 to C 30 arylalkyl group, a substituted or unsubstituted C 6 to C 30 aryl group, a substituted or unsubstituted C 1 to C 30 alkoxy group, a substituted or unsubstituted C 6 to C 30 aryloxy group (—OR 11 , wherein R 11 is a substituted or unsubstituted C 6 to C 30 aryl group), a substituted or unsubstituted C 4 to C 30 cycloalkyl group, a substituted or unsubstituted C 4 to C 30 cycloan alkyloxy group (—OR 12 , wherein R 12 is a substituted or unsubstituted C 4 to C 30 cycloalkyl group), a substituted or unsubstituted C 2 to C 30 heteroaryl group, an acyl group (—C(═O)R 13 , wherein R 13 is a substituted or unsubstituted C 1 to C 30 alkyl group), a sulfonyl group (—S(═O)R 14 , wherein R 14 is a substituted or unsubstituted C 1 to C 30 alkyl group), and a carbamate group (—NH 2 COOR 15 , wherein R 15 is a substituted or unsubstituted C 1 to C 30 alkyl group), each of —Ar 1 — and —Ar 2 — are independently one of substituted or unsubstituted C 4 to C 20 aromatic ring, a substituted or unsubstituted C 4 to C 14 heteroaromatic ring and a substituted or unsubstituted C 6 to C 30 condensed polycyclic group including a heteroaromatic ring, provided that —Ar 1 — and —Ar 2 — are not a thiazolo[4,5-g]-benzo-2′,1′,3′-thiadiazole structural unit, and a, b 1 , and b 2 represent a mole ratio of each structural unit, a ranges from about 1 mol % to about 99 mol %, and b 1 +b 2 ranges from about 1 mol % to about 99 mol % based on 100 mol % of a, b 1 , and b 2 .
