π-extended phosphepines: redox and optically active P-heterocycles with non-planar framework

Résumé

In this letter, we present the synthesis of a new family of pi-extended dithieno[b,f]phosphepines. The Pd-catalyzed direct-arylation allows the introduction of various substituents, which tune the absorption/emission in the visible range as well as the redox properties. All those modifications were rationalized through DFT calculations. The physical properties of ambipolar phos-phepine with diphenylamino substituents conduct us to use it as a semiconductor in a p-type organic field-effect transistors (OFETs).
