TCNQ
Order Code: M681
7,7,8,8-tetracyanoquinodimethane, known as TCNQ has a LUMO at 4.5 eV and is most known for the charge transfer salts formed by its radical anion TCNQ in photovoltaics and light-emitting diodes and organic field-effect transistor devices. TCNQ and its derivatives have been used as dopants, leading to an increase in the hole mobility or to the lowering of injection barriers.
