Naphthalenetetracarboxylic diimide (NTCDI) is a solid
organic compound In chemistry, organic compounds are generally any chemical compounds that contain carbon- hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. Th ...

Properties

NTCDI is redox-active, forming stable radical anions near -1.10 V vs. Fc/Fc+. Its ability to accept electrons reflects the presence of an extended conjugated ring system and the electron withdrawing groups (carbonyl centers). NDI is used in supramolecular chemistry owing to its tendency to form charge-transfer complexes with
crown ether In organic chemistry, crown ethers are cyclic chemical compounds that consist of a ring containing several ether groups (). The most common crown ethers are cyclic oligomers of ethylene oxide, the repeating unit being ethyleneoxy, i.e., . I ...
s, e.g., to give rotaxanes and catenanes. As another consequence of their planar structure and electron-acceptor properties, NDIs intercalate into DNA. It is also suitable for fabrication of soft electronic devices.
