Dyes with a similar structure, i.e., a combination of triphenylamine with cyanovinylenethiophene, have been synthesized before and have been used in different applications according to Spraul et al., (2004); Roquet et al., (2006); and Hagberg et al., (2006) (2007) (2008).. Specifically, Roquet et.al. described star-shaped mols. that were applied in org. heterojunction solar cells. The authors have presented dyes with similar structure for n-type (TiO2) dye-sensitized solar cells.
