The optical properties of the oligothiophene–tetrathiafulvalene system are greatly affected by structural factors. An understanding of these, as presented here, is a first step towards reducing the band gap in thiophene oligomers and thus optimizing them for device applications. The effect of spacer length and the role of planarity and rigidity, for example of the syn conformation shown in the Figure, are investigated.
