PROBLEM TO BE SOLVED: To provide a novel quarterpyridine derivative, a complex containing the same, a photoelectric conversion element and a dye-sensitized solar cell. It is represented by the following formula (I): In the formula (I), R 1 , R 2 , R 3 and R 4 are each independently —OR ′, —COOR ′, —CONR ′, —CHO, —CH 2 OR ′, —CN, —COONR ′, etc. R ′ represents hydrogen or an alkyl group having 1 to 4 carbon atoms, m1 and m4 represent an integer of 0 to 4, m2 and m3 represent an integer of 0 to 3, a quarterpyridine derivative, A complex, a photoelectric conversion element, and a dye-sensitized solar cell.
