title: Incorporating TCNQ into thiophene-fused heptacene for n-channel field effect transistor.
abstract: Incorporation of electron-deficient tetracyanoquinodimethane (TCNQ) into electron-rich thiophene-fused heptacene was successfully achieved for the purpose of stabilizing longer acenes and generating new n-type organic semiconductors. The heptacene-TCNQ derivative 1 was found to have good stability and an expected electron transporting property. Electron mobility up to 0.01 cm(2) V(-1) s(-1) has been obtained for this novel material in solution processed organic field effect transistors.
