Abstract

A novel heteroleptic ruthenium complex carrying a heteroaromatic-4,4′-π-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 standard global AM 1.5 sunlight.
