Thiophene‐based materials for n‐type semiconductor devices? A new strategy towards this goal that consists of chemically transforming the thienyl sulfurs into the corresponding S , S ‐dioxides (see Figure) is described. This is shown—for quarter‐ and quinquethiophenes—to lead to very stable oligomers with increased electron delocalization and electron affinity.
