- Аннотация: 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 by an effective strategy based on the Fiesselmann thiophene and the Fischer indole synthesis. The new molecules exhibit a large optical band gap (2.82 eV <Egopt <3.23 eV) and their highest occupied molecular orbital (HOMO) energy formed by plane π-core ranges between -5.2 and -5.6 eV, with the narrower optical band gap and lower HOMO level correspond to selenated heteroacenes. In thin solid films of the heteroacenes, hole mobility measured by the conventional CELIV technique ranges between 10-5 and 10-4 cm2V-1s-1. All these make the proposed condensed-ring compounds a promising platform for the development of hole transporting materials applicable in organic electronics.
