Patent ID: 7550554

Claim:
An organic semiconductor material comprising: a polymer comprising a repeat unit represented by the following formula (I): wherein, Ar 1 represents a substituted aromatic hydrocarbon group or a non-substituted aromatic hydrocarbon group, Ar 2 and Ar 3 each, independently, represent a divalent aromatic hydrocarbon selected from the group consisting of substituted or non-substituted monocyclic aromatic hydrocarbons, substituted or non-substituted non-condensed polycylic aromatic hydrocarbons and substituted or a non-substituted condensed polycylic aromatic hydrocarbons and Ar 4 represents a bivalent group of benzene, thiophene, biphenyl or anthracene, each of which can optionally have a substituent; and a compound represented by the following formula (VII): wherein, n is 0 or 1, Ar′ represents a substituted aryl group or a non-substituted aryl group, R 13 and R 14 each, independently, represents a hydrogen atom, a substituted or non-substituted alkyl group, or a substituted or non-substituted aryl group, wherein Ar′ and R 13 can optionally combine to form a ring, A represents a 9-anthryl group, a substituted or non-substituted carbazolyl group, a group represented by the following formula (1), or a group represented by the following formula (2): wherein R 15 and R 16 each, independently, represents a hydrogen atom, an alkyl group, alkoxyl group, a halogen atom or a group represented by the following formula (3): wherein, R 17 and R 18 each, independently, represents a substituted or non-substituted alkyl group or a substituted or non-substituted aryl group, wherein R 17 and R 18 can optionally combine to form a ring.
