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.
作为场效应晶体管有机半导体的2,6 - 二苯基苯并[1,2 - b:4,5 - b']二硫属元素苯，包括噻吩、硒吩和碲吩类似物，由市售的1,4 - 二溴苯通过三步有效合成。所有三种苯并二硫属元素苯均作为良好的p型半导体，特别是硒吩类似物2,6 - 二苯基苯并[1,2 - b:4,5 - b']二硒吩，表现出0.17 cm2 V-1 s-1的高场效应晶体管迁移率。
