Abstract
A platinum complex represented by the formula PtL,/L,or PtLX,/LX,wherein L,and L each represent a ligand selected from the group consisting of 2,2′-bipyridine compounds having at least one anionic group and 1,10-phenanthroline compounds having at least one anionic group, L,represents a dithiolate selected from those represented by the formulas (a) through (d) shown in the specification, and X,and X,each represent a thiolate selected from those represented by the following formulas (e) and (f) shown in the specification. A dye-sensitized electrode includes a substrate having an electrically conductive surface, an oxide semiconductor film formed on the conductive surface, and the above platinum complex supported on the film. A solar cell includes the above electrode, a counter electrode, and an electrolyte disposed therebetween.
