<P>PROBLEM TO BE SOLVED: To provide a novel pigment which has a large absorption of light in the visible light region and is expected to obtain a pigment-sensitized solar cell exhibiting high conversion efficiency and a compound which is utilized as a ligand of the pigment. <P>SOLUTION: The compound is represented by formula (1) (wherein X is nitrogen or the like; R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>are each hydrogen or a 1-40C hydrocarbon group; R<SP POS="POST">3</SP>is hydrogen, a halogen, a hydroxyl group or the like; R<SP POS="POST">4</SP>is hydrogen or a 1-40C hydrocarbon group; and R<SP POS="POST">5</SP>is hydrogen, a hydroxyl group or a 1-40C alkoxy group) and the pigment has a ligand represented by the formula (1). This pigment has a large absorption of light in the visible light region and is expected to exhibit high conversion efficiency when used in a pigment-sensitized solar cell. <P>COPYRIGHT: (C)2012,JPO&INPIT |
