The preparation of thiophene-S,S-dioxides and their role in organic electronics

In the last decade, Rozen's reagent (HOF center dot CH3CN) has been shown to be powerful yet selective enough to oxidize thiophene moieties in various environments. The resulting thiophene-S,S-dioxides display attractive properties for electronic devices, in particular a reduced HOMO-LUMO band gap. This highlight illustrates how utilizing this unprecedentedly potent oxidizing agent allows access to an exciting new family of molecules that show great promise for semiconductors.
