A new organic multifunctional material, a rigid core thiophene oligomer, has been designed and synthesized. In both solution-processed and vacuum-sublimed films, the delicate balance of forces needed to obtain a supramolecular organization that imparts good charge transport and electroluminescence has been achieved, with the films being successfully employed as active layers in organic light-emitting (field-effect) transistors (see Figure).
