A photosensitizer complex of formula (I) MLX<SUB>2 </SUB>in which M is a transition metal selected from ruthenium, osmium, iron, rhenium and technetium; each X is a co-ligand independently selected from NCS<SUP>-</SUP>, Cl<SUP>-</SUP>, Br<SUP>-</SUP>, I<SUP>-</SUP>, CN<SUP>-</SUP>, H<SUB>2</SUB>O; pyridine unsubstituted or substituted by at least one group selected from vinyl, primary, secondary or tertiary amine, OH and C<SUB>1-30 </SUB>alky, preferably NSC<SUP>-</SUP> and CN<SUP>-</SUP>. L is a tetradentate polypyridine ligand, carrying at least one carboxylic, phosphoric acid or a chelating group and one substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, substituted or unsubstituted alkylamide group having 2 to 30 carbon atoms or substituted or unsubstituted aralkyl group having 7 to 50 carbon atoms. A dye-sensitized electrode includes a substrate having an electrically conductive surface, an oxide semiconductor film formed thereon, and the above sensitizer of formula (I) as specified above, supported on the film.
