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.

Abstract
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.File in questo prodotto:
