| Summary: | 碩士 === 國立成功大學 === 化學系碩博士班 === 100 === The synthesis and physical characterizations of the 4 new organic compounds that proposed in this study were based on the acenaphtho[1,2k]fluoranthene3,4,10,11tetracarboxylic diimide. Among the four, there were two compounds which the core composition were equipped with up to strong electronwithdrawing group (F、CN) in
the 7,14positions in order to enhance the electron affinity.
Those compounds were prepared via palladiumcatalyzed reaction. Our strategy is to use Suzuki coupling to connect two of 1,8naphthalimide and benzene together, and then form the intramolecular cyclization with twice CH bond activation
We used cyclic voltammetry to examine the influence of the substituents on the LUMO level, and calculated the energy gap (Eg) by through UV/Vis spectra. According to the result of these two measurements, we compared 47 to its similar structures and to explain the difference between them. The 46 and 47 were constructed to the organic thin film transistor (OTFT) devices. Fluoridesubstituted (47) exhibited ntype semiconducting behavior and showed electron mobility up to 4.0 × 10-4 cm2/Vs. The new organic material in this study which with high mobility will write a new page for the organic electronics.
