Abstract
The present invention relates to compounds of general formula I wherein Rand Rare each independently hydrogen, C-C-alkyl which in case of C-alkyl may be interrupted by one and in case of C-C-alkyl by one or two nonadjacent oxygen atoms, C-C-cycloalkyl, aryl, aryl-C-C-alkyl or aryloxy-C-C-alkyl, D is an m-valent (m=1, 2 or 3) donor moiety which comprises at least one carbon-carbon or carbon-heteroatom double bond and/or at least one unfused or fused carbo- or heterocyclic ring, A is an acceptor moiety which comprises at least one carbon-carbon or carbon-heteroatom double bond and/or at least one unfused or fused carbo- or heterocyclic ring, and the donor moiety D and the acceptor moiety A are π-conjugated to one another. Furthermore, the present invention relates to the use of compounds of formula I for producing dye-sensitized solar cells and to dye-sensitized solar cells comprising compounds of formula I.
