A well-defined series of long and soluble isoindigo thienoacene oligomers have been synthesized from a novel electron deficient building block: benzo[1,2-b:4,5-b′]bis[b]benzothiophene bislactams. Extension of the π-conjugated systems facilitates control of the optical, electronic and device characteristics.
