Abstract

Electron-transporting (n-type) organic semiconductors [1] are relatively rare, but of great interest for “plastic electronics” such as thin-film transistors (TFTs), organic light-emitting diodes (OLEDs), and photovoltaics.[2] The most prominent examples of TFT n-type materials have been obtained by modifying known p-type cores with strongly electronegative fluoro/fluoroalkyl substituents. However, despite these advances, those factors underlying ...
