A new N-type organic semiconductor synthesized by knoevenagel condensation of truxenone and ethyl cyanoacetate.
A novel n-type organic semiconductor, Et-TITC, was synthesized by Knoevenagel condensation of truxenone and ethyl cyanoacetate. Ultrasonication improved the yield of Et-TITC by more than 10 times. The molecular structure of Et-TITC was determined by X-ray analysis. Et-TITC possesses a large electron affinity and excellent solubility in many organic solvents. A positively charged xerographic photoreceptor with an excellent photosensitivity (E 1/2) of 0.32 microJ cm(-2) was prepared using Et-TITC as the charge-transport material. [structure: see text]
