A series of heteroaromatic 4,4′-π-conjugated 2,2′-bipyridines (bpy) bearing conjugated π-excessive and π-deficient heteroaromatic rings as donor (D) and acceptor (A) substituents, respectively, is presented. We have experimentally and computationally found that, upon variation of donor and acceptor properties of the heterocyclic subunits in combination with different structural symmetries (bpy-π-D

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.
