2,3,5,6-Tetrafluoro-7,7,8,8-tetracyanoquinodimethane Usage And Synthesis
ClassificationFluorinated compounds, p-type dopant, Strong electron acceptor, Hole-injection materials, Hole-transport layer material, OLEDs, Polymer Solar Cells, Perovskite Solar Cells, OFETs.
ApplicationsF4TCNQ is one of the most widely used and most effective p-type dopants due to its strong electron-accepting ability and the extended π system. It has a deep LUMO level (-5.2 eV) which is energetically in the vicinity of the HOMO level of many organic semiconductors. Doping is facilitated by charge transfer from the HOMO level of the host to the LUMO of the dopant molecule. Pin devices with F4TCNQ doped 4,4',4''-tris(3-methylphenylphenylamino)triphenylamine (m-MTDATA) serving as the p-doped HTL show high luminance and efficiency at extremely low operating voltages: For instance, a luminance of 1000 cd/m2 is reached at a voltage of 2.9 V.
It has been reported that by controlling the doping concentration, the PCE of the PCDTBT:F4TCNQ solar cells increased from 6.41% to 7.94%, mainly due to improving the photocurrent with a F4TCNQ weight ratio of the blend lower than 0.5% [2]. F4TCNQ is also used as the p-type dopant for graphenes.

Chemical PropertiesYellow-greenish or orange-brown powder
UsesF4-TCNQ is the p-type dopant for hole-only devices and field effect transistors with organic hole transport layers (HTL). It is used in the preparation of a bilayer structure of F4-TCNQ and pentacene to study improved thermoelectric performance of organic thin films.
General Description2,3,5,6-Tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4-TCNQ) is a dopant used in the fabrication of organic semiconductors. It can tune the electronic properties as its lowest unoccupied molecular orbital is at a desirable energy level required to oxidize a wide range of semiconductors.
