Abstract

As novel bis (pyrrolo [3, 4-d]) tetrathiafulvalene (PyTTF)-based organic semiconductors, N- acyl-substituted PyTTFs 4 were synthesized and evaluated. Their oxidation potentials determined by cyclic voltammetry were shifted cathodically by more than 0.35 V compared with the N-alkyl-PyTTFs 3. In accordance with elevated oxidation potentials, their vapor- processed field-effect transistors showed improved air-stability with mobilities up to 0.08 ...
