Application: Electron-acceptor molecule used to form charge-transfer superconductors.
Application: Tetrathiotetracene (TTT) and TNCQ can be thermally co-deposited to form n-type thin films with a power factor of 0.33 μWm-1K-2 and an electrical conductivity of 57 Sm-1 to fabricate thin film organic thermoelectric generators. It can be used to functionalize chemical vapor deposited (CVD) graphene and form a p-doped nanocomposite that finds potential application as a conductive anode for organic solar cells (OSCs). Electrochemical sensors can be developed by using TNCQ and graphene oxide to form a glassy electrode for the detection of reduced glutathione (GSH).
General description: 7,7,8,8-Tetracyanoquinodimethane (TNCQ) is a strong electron acceptor as it has four cyano groups and π-conjugation bonds that form charge transferring chains and ion radical salts which are mainly used as p-dopants for the fabrication of a variety of semiconductor applications.
