Abstract

2,6-Diphenylbenzo[1,2-b:4,5-b′]dichalcogenophenes including thiophene, selenophene, and tellurophene analogues as organic semiconductors for field-effect transistors were effectively synthesized in three steps from commercially available 1,4-dibromobenzene. All three benzodichalcogenophenes acted as good p-type semiconductors, and particularly the selenophene analogue, 2,6-diphenylbenzo[1,2-b:4,5-b′]diselenophene, showed high FET mobility of 0.17 cm2 V-1 s-1.
