A novel heteroleptic Ru complex carrying a heteroarom.-4,4'-.pi.-conjugated 2,2'-bipyridine [Ru(II)LL'(NCS)2] (L = 4,4'-bis[(E)-2-(3,4-ethylenedioxythien-2-yl)vinyl]-2,2'-bipyridine, L' = 4,4'-(dicarboxylic acid)-2,2'-bipyridine) was synthesized and used in dye-sensitized solar cells, yielding photovoltaic efficiencies of 9.1% under std. global AM 1.5 sunlight.
