Evidence for the contribution of sulfur–bromine intramolecular interactions to the self-rigidification of thiophene-based π-conjugated systems
Résumé
Bithiophene associating 3,4-ethylenedioxythiophene and 3-bromothiophene, and the corresponding polymer exhibit self-rigidified structures of the conjugated backbones resulting from the association of S–Br and S–O non-bonded intramolecular interactions.
