Abstract
We report an organic semiconductor, tetrabenzoporphyrin, that can be used for transistor applications. It can be derived from a soluble precursor compound with bicyclo structure. The precursor film is amorphous and shows good film morphology. Then it is converted into an insoluble crystalline semiconductorfilm quantitatively at elevated temperature of 150–200 °C. Field-effect transistors were fabricated by this method. Observed mobility of the devices exceeded 10 −2 cm 2 / V s with appropriate process and device structure.Keywords
