Organic Field-effect transistors have been developed for many years. Both P-type and N-type materials are indispensable parts of the application. However, the development of N-type materials is far less than that of P-type materials. This study is to design and synthesis molecular for N-type OFET in the air. We design and synthesis 4,7-bis(dithiothienoimide)benzo[2,1,3]thiadiazole. To reduce the LUMO value, we converted the imide to thioimide. We successfully synthesized BTIBT-C2C6 and BTIBT-C12. The difference between is their alkyl side chains, which are 1-Octyl and 2-Ethyl-hexyl. The optical properties, electrochemical properties and thermal stability of the compounds were also investigated. The LUMO energy levels of BTIBT-C2C6 and BTIBT-C12 are -3.80 eV and -3.75 eV. According to the data, they have good thermal stability. Therefore, in the process of component, not only vacuum evaporation technology can be used, solution process also can be used base on the good solubility. The two compounds have good potential in organic semiconductor and are expected to be N-type OFET materials.
