A pentacene derivative, tetramethylpentacene, was synthesized and single cyrstals of the derivative were obtained by gradient sublimation. Reorganization energy of tetramethylpentacene was found similar to that of pentacene. Thin film transistors fabricated with the derivative showed a higher charge transport mobility with the bottom-contact mode device prepared with deposition substrate temperature of 25°C.
