title: Cyanated diazatetracene diimides with ultrahigh electron affinity for n-channel field effect transistors.
abstract: Several diazatetracene diimides with high electron affinity (up to 4.66 eV!) were prepared and well characterized. The LUMO energy level of these electron-deficient molecules was found to be closely related to their material stability. Compound 7 with ultrahigh electron affinity suffered from reduction and hydrolysis in the presence of silica gel or water. The stable compounds 3 and 6 showed n-channel FET behavior with an average electron mobility of 0.002 and 0.005 cm(2) V(-1) s(-1), respectively, using a solution processing method.
