Orgnaic field-effect transistors (OTETs) are of great interest in applications such as display drivers, identification tags, and smart cards because they have the advantages of being inexpensive, flexible, and lightweight. Hole mobilities in anthracene single crystals were measured by the time-of-flight photocurrent technique and were found to reach up to 3 cm2V-1s-1 at 300K. Although anthracene may be a good candidate for a p-type semiconductor for organic field-effect transistors (OFETs). The HOMO energy level in linear [n]acenes (n=2: naphthalene, 3: anthracene, 4: tetracene, 5: pentacene) significantly increases with increasing n, which facilitates the formation of radical cations (holes) at the interface between a dielectric and a semiconducting layer. Furthermore, the extended  system of a higher acene enhances the intermolecular overlap of p–p systems in the solid state and leads to high mobility. In this paper, we report synthesis and characterize of symmetrical anthracene derivatives for OTFTs.
