F4-TCNQ, also known as 2,3,5,6-Tetrafluoro-7,7,8,8-tetracyanoquinodimethane (CAS 29261-33-4), is a highly efficient electron acceptor widely used in organic electronics, semiconductor research, and advanced functional materials. With its strong electron-withdrawing groups, F4-TCNQ exhibits very high electron affinity, making it one of the most effective p-type dopants for organic semiconductors.
Chemical Characteristics
F4-TCNQ appears as a dark green to black crystalline solid. Its structure contains multiple cyano groups and fluorine substituents, which significantly enhance its electron-accepting ability compared to traditional acceptors such as TCNQ. This allows it to form stable charge-transfer complexes with a wide range of electron-donating organic materials.
Applications
