摘要

The performance of organic field effect transistors using the small molecule, tri-isopropyl- silane-di-benzo chrysene (TIPS-DBC) is reported. The field effect mobility FE is found to depend on the deposition conditions, which affect the morphology of the film. A mobility in the range of 1.5×10 ~(-6) to 2.4×10 ~(-4)cm ~2V ~(-1)s ~(-1) is obtained from the evaporated films depending on the substrate treatment and deposition temperature, while films deposited by solution-processing techniques yield mobilities in the range of 0.7×10 ~(-3) to 1.5×10 ~(-3)cm ~2V ~(-1)s ~(-1). The enhanced performance in polycrystalline solution-processed coatings and its relationship to crystallite size is an important parameter in the design of high-performance devices based on small molecules.
