Published: May 2016

AbstractA series of anchor‐functionalized cyclometalated bis(tridentate) ruthenium(II) triarylamine hybrids [Ru(dbp‐X)(tctpy)]2− [2 a]2−–[2 c]2− (H3tctpy=2,2′;6′,2′′‐terpyridine‐4,4′,4′′‐tricarboxylic acid; dpbH=1,3‐dipyridylbenzene; X=N(4‐C6H4OMe)2 ([2 a]2−), NPh2 ([2 b]2−), N‐carbazolyl [2 c]2−) was synthesized and characterized. All complexes show broad absorption bands in the range 300–700 nm with a maximum at about 545 nm. Methyl esters [Ru(Me3tctpy)(dpb‐X)]+ [1 a]+–[1 c]+ are oxidized to the strongly coupled mixed‐valent species [1 a]2+–[1 c]2+ and the RuIII(aminium) complexes [1 a]3+–[1 c]3+ at comparably low oxidation potentials. Theoretical calculations suggest an increasing spin delocalization between the metal center and the triarylamine unit in the order [1 a]2+<[1 b]2+<[1 c]2+. Solar cells were prepared with the saponified complexes [2 a]2−–[2 c]2− and the reference dye N719 as sensitizers using the I3−/I− couple and [Co(bpy)3]3+/2+ and [Co(ddpd)2]3+/2+ couples as [B(C6F5)4]− salts as electrolytes (bpy=2,2′‐bipyridine; ddpd=N,N′‐dimethyl‐N,N′‐dipyridin‐2‐yl‐pyridine‐2,6‐diamine). Cells with [2 c]2− and I3−/I− electrolyte perform similarly to cells with N719. In the presence of cobalt electrolytes, all efficiencies are reduced, yet under these conditions [2 c]2− outperforms N719.
