AbstractIncorporation 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. © 2012 American Chemical Society.
