2,3,5,6-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.
2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4-TCNQ) are p-type molecules, used as a strong acceptor dopant , it generates free holes.
F4-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.
F4-TCNQ can be doped with poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA) to form a hole transport material (HTL), which can be used to achieve an energy efficiency of 16% for a semi-transparent perovskite solar cell. It can be used as a p-type dopant to form a blended composite film with poly(3-hexylthiophene) (P3HT) having enhanced charge mobility, which can be potentially useful in organic photovoltaics.
