Benzo[1,2-b:4,5-b']dithiophenes were oxidized under mild conditions with m-CPBA to yield the corresponding bis-sulfones (or tetraoxides). These sulfones possess red-shifted absorption and emission spectra relative to the parent molecules. Electrochemical analyses reveal that the benzodithiophene molecules are transformed from electron donors to electron acceptors.

diimide(PMDI)‐based polymers—poly(pyromellitic diimide‐co‐bithiophene) [poly(PMDI‐BTh)], poly(pyromellitic diimide‐co‐tetrathiophene) [poly(PMDI‐TTh)], and poly(pyromellitic diimide‐co‐benzodithio‐ phene) [poly(PMDI‐BDTTh)]—are synthesized to study the influence of different thiophene‐containing electron‐donating groups on the crystallizability of PMDI‐based conjugatedpolymers.
