“…In thin solid layers, the charge carrier mobility was measured using the technique of charge extraction by linearly increasing voltage (CELIV) . Metal-insulator-semiconductor (MIS) diode structures, similar to those described earlier, , were prepared. Onto the ITO (indium-tin oxides) electrode of the ITO/glass substrate, a SiO 2 insulator layer of 70 nm in thickness was deposited by conventional magnetron sputtering.…”

Two series of new N,S,Se-heteroacenes, namely, 6H-benzo[4′,5′]selenopheno[2′,3′:4,5]thieno[3,2-b]indoles and 12H-benzo[4″,5″]selenopheno[2″,3″:4′,5′]thieno[2′,3′4,5]thieno[3,2-b]indoles, were successfully obtained using an effective strategy based on Fiesselmann thiophene and Fischer indole synthesis. The new molecules exhibit a large optical band gap (2.82 eV < E g opt < 3.23 eV) and their highest occupied molecular orbital (HOMO) energy formed by the plane π-core ranges between −5.2 and −5.6 eV, with the narrower optical band gap and lower HOMO level corresponding to selenated heteroacenes. In thin solid films of the heteroacenes, hole mobility measured using the conventional CELIV technique ranges between 10–5 and 10–4 cm2·V–1·s–1. All these make the proposed condensed-ring compounds a promising platform for the development of hole-transporting materials applicable in organic electronics.

Herein, we describe the synthesis of unsymmetrically substituted dibenzo[f,h]furazano [3,4-b]quinoxalines by intramolecular cyclization through direct transition metal-free C−H functionalization. The electrochemical and photophysical properties for several polycycles have been measured. In thin films of the dibenzo[f,h]furazano[3,4-b]quinoxalines, hole mobility is in the order of 10 −4 cm 2 V −1 s −1 . The results show that the HOMO and LUMO energy levels are appropriate for using the compounds as hole-transport materials in thin-film devices, in particular, organic and perovskite solar cells.
