Organic Light-Emitting Transistors Based on Solution-Cast and Vacuum-Sublimed Films of a Rigid Core Thiophene Oligomer

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).
