7,7,8,8-Tetracyanoquinodimethane (TCNQ)(CAT: M047278) is a strong electron acceptor widely employed in organic electronics and materials research. Its quinoid structure and multiple cyano groups provide high electron affinity, making it a key component in charge-transfer complexes and organic semiconductors. TCNQ is frequently used to modify electrode interfaces, enhance conductivity, and stabilize charge transport in organic field-effect transistors (OFETs), organic photovoltaics (OPVs), and sensors. It also plays an important role in the study of molecular conductors and low-dimensional electronic systems. With its well-defined redox behavior and versatility, TCNQ remains a cornerstone material in organic optoelectronic device engineering and fundamental research.
