<p><P>PROBLEM TO BE SOLVED: To provide a new polymer that can be used as an organic semiconductor material. <P>SOLUTION: The polymer contains a repeating unit represented by general formula (1) (wherein R<SP POS="POST">a</SP>is a hydrocarbon which may have a heteroatom; R<SP POS="POST">b</SP>to R<SP POS="POST">d</SP>are each independently hydrogen, halogen or hydrocarbon which may have a heteroatom; R<SP POS="POST">e</SP>and R<SP POS="POST">f</SP>are each independently hydrogen, halogen or hydrocarbon which may have a heteroatom; X<SP POS="POST">a</SP>represents nitrogen or carbon bonded to hydrogen or substituent; X<SP POS="POST">b</SP>represents oxygen or sulfur; X<SP POS="POST">c</SP>represents carbon, silicon or nitrogen; m represents 1 or 2; R<SP POS="POST">b</SP>to R<SP POS="POST">d</SP>may be bonded to each other to form a ring; and R<SP POS="POST">a</SP>to R<SP POS="POST">f</SP>may each independently have a further substituent). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
