Abstract:
To achieve rationalization criteria for target-oriented molecular design of Th–X–Th (Th = thiophene)
semiconductor building blocks, we have carried out an extensive investigation on the effects of the X
core (X = fluorene, carbazole or phenothiazine) on the electronic properties and polymerization ability
of Th–X–Th monomers and on the electronic and structural properties of the corresponding periodic
conducting polymers –(Th–X–Th)n–, obtained by electropolymerization and, for comparison’s sake, by
FeCl3-catalyzed polymerization and/or Suzuki coupling. The effects of molecule bending and of solubilising
bulky alkyl substituents have also been considered. The systematic, exhaustive template sequence
combined with a rigorous, multitechnique investigation protocol affords a unique data library and a
complete set of reliable interpretative/predictive guidelines.
