Abstract

We herein report on an efficient synthesis of diacenaphthylene-fused benzo[1,2-b:4,5-b′]dithiophenes and demonstrate that their packing structure in the solid state depends on the substituent groups. These compounds form dimers with their radical cations in high concentration solution and exhibit good field-effect mobility.
