Single-crystalline submicrometer-sized ribbons of copper phthalocyanine (CuPc) have been synthesized (see Figure). Organic field-effect transistors (OFETs) fabricated using individual ribbons of CuPc exhibit high mobilities and low threshold voltages. These characteristics are highly reproducible and stable, indicating the high quality of the transistors. Moreover, CuPc submicrometer-sized ribbons show excellent flexibility, which may lead to their application in flexible electronics.
