Hypofluorige Säure , ein starkes und selektives Oxidationsmittel, kann mit thiophenhaltigen Polymeren reagieren und deren optoelektronische Eigenschaften verändern. Wie L. M. Campos et al. in der Zuschrift auf S. 1863 ff. berichten, werden die Thiopheneinheiten in nichtaromatische Thiophen‐1,1‐dioxide umgewandelt, was die Elektronenaffinität der Materialien erhöht und ihre Bandlücke verkleinert. Das...
The use of Rozen’s reagent (HOF⋅CH3CN) to convert polythiophenes to polymers containing thiophene‐1,1‐dioxide (TDO) is described. The oxidation of polythiophenes can be controlled with this potent, yet orthogonal reagent under mild conditions. The oxidation of poly(3‐alkylthiophenes) proceeds at room temperature in a matter of minutes, introducing up to 60 % TDO moieties in the polymer backbone. The...
