Ultrathin nanocrystals with thicknesses of only several monolayers and even a single monolayer were prepared via exfoliation by ultrasound from an octamethyl substituted zinc(II) phthalocyanine (ZnMe2Pc). The drop-casted thin films of these nanocrystals exhibited higher crystallinity than that of the vacuum-deposited film. The drop-casted field-effect transistor based on these nanocrystals showed a significant increase in charge carrier mobility because of enhanced intermolecular pi-pi stacking in the ultrasonic-treated ZnMe2Pc, and the measured mobility was two orders of magnitude higher than that of the vacuum-deposited transistor.
