N-shaped organic semiconductors are synthesized via four steps from a readily available starting material. Such semiconductors exhibit preferable ionization potential for p-type operation, thermally stable crystalline phase over 200 degrees C, and high carrier mobility up to 16 cm 2 V-1 s(-1) (12.1 cm(2) V-1 s(-1) on average) with small threshold voltages in solution-crystallized field-effect transistors.
