TCI T1131 Tetrafluorotetracyanoquinodimethane (F4-TCNQ, CAS 29261-33-4), purified by sublimation, is a strongly electron-accepting organic compound. It belongs to the electronic materials and molecular conductors category. In the laboratory it is used to create charge-transfer complexes and to dope organic semiconductor materials. Sublimation purification indicates that the product is intended for materials research that is sensitive to impurities, where the quality of the starting compound directly affects the reproducibility of results.

The main property that makes this compound a preferred choice is its high electron affinity, which lets the molecule readily accept electrons from donor species. This leads to the formation of salts or charge-transfer complexes with characteristic electrical behavior. The fluorine atoms on the TCNQ framework increase its electron-withdrawing ability compared with ordinary TCNQ. In organic thin films, an acceptor of this type can raise the concentration of positive charge carriers, which is the basis of p-type doping. Researchers also use it to study conductivity and intermolecular charge movement.

In Indonesia, this material is relevant to research groups working in materials science, organic electronics, and photovoltaics at universities and research institutions. The 100 mg and 1 g pack sizes suit small-scale research, where only limited quantities are needed for each experiment. Laboratories typically use it for doping studies, charge-transfer experiments, and the preparation of thin-film samples for electrical characterization.
