The overall efficiencies of the cell dramatically dropped when the donor group was replaced by a quinoxaline unit, as in the following dyes 11–13.The use of a dithienothiophene unit in 12 instead of a bithiophene in 11 further reduced the cell efficiency, which was explained by aggregation of the dye. The further reduced efficiency in the case of 13 with thienylenevinylene units was ascribed to possible cis–trans photoisomerizationof the C=C bonds.
