    • Abstract

       

      We investigate the molecular orientation transition and resulting morphology of copper phthalocyanine (CuPc) thin films induced by solvent–vapour annealing (SVA) in detail. Seven solvents are utilized to tune the morphology of CuPcthin films. The morphology, crystalline structure and optical properties of the CuPc active layer were investigated through field emission scanning electronmicroscopy (FESEM),X-ray diffraction (XRD) and ultraviolet–visible (UV–Vis) absorption spectrum, respectively. The result demonstrates that morphology and structure are depended on the type of solvents. Thehigh crystallinity of the CuPc films with a larger grain size and less grain boundaries can be observed. As a result, the resistance of the conducting channel is decreased, leading to an improved performance of the organic field-effect transistor (OFET).
