Abstract: Herein, we have studied how the processing of organic semiconductors can affect their morphology and crystal structure. p-type and n-type organic semiconductors have been employed as active layers in Organic Field-Effect Transistors (OFETs). The purpose of the work carried out has been elucidating the correlation of the molecular structure, crystal packing and thin film morphology with the electrical properties of the organic semiconductor. Further, aiming at enhancing the performance and stability of the devices, the organic semiconductors used in this thesis were blended with polymer binders. In addition, the effect of the polymer binder has been studied in detail by comparing OFETs based on thin-films of the pristine.
