A ruthenium complex, which is represented by the following formula (I):whereinL is 2,2'-bipyridyl-4,4'-dicarboxylic acid, 2,2'-bipyridyl-4,4'-disulfonic acid, or 2,2'-bipyridyl-4,4'-diphosphonic acid;A is N'R1R2R3R4.,wherein R1is C5-20alkyl, phenyl, or benzyl, R2, R3, and R4are each independently C1-20alkyl, phenyl, or benzyl, R5, R6, and R7are each independently C1-20alkyl; andm is an integral of 1-4. The ruthenium complex is suitable for Dye-Sensitized Solar Cell (DSSC). Hence, the photoelectric characteristics of the DSSC manufactured with the ruthenium complex of the present invention can be improved. |
