present the synthesis of a new family of π-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 phosphepine
with diphenylamino substituents inspired us to use it as a semiconductor
in p-type organic field-effect transistors (OFETs).
