Document Type and Number:
WIPO Patent Application WO/2012/017869
Kind Code:
A1
Abstract:
[Problem] To provide a metal complex dye, a photoelectric conversion element and a photoelectrochemical cell with a high conversion efficiency and excellent durability. [Solution] A metal complex dye comprising a ligand LL1 represented by formula (I). [In the formula, R1 and R2 each represents a divalent group represented by general formula (II), etc., L1 and L2 each represents a single bond or an ethenylene group, etc., R3 and R4 each represents a hydrogen atom or an alkyl group, etc., R' and R'' each represents a substituent, A1 and A2 each represents an acidic group or a group having an acidic group, n1 and n2 each represents an integer of 0 to 3, and n3 and n4 each represents an integer of 0 to 3.] [In general formulas (II) to (XX), B1 to B37 each represents a sulfur atom, etc., R5 to R57 each represents a hydrogen atom or an alkyl group, etc., and m1 to m19 each represents an integer of 1 to 5. The left side bonds of the general formulas (II) to (XX) are located on the L1 side or L2 side in the formula (I) and are bound to the pyridine ring either directly or via L1 or L2.]
