PANiCNQ is plastic magnet made of a combination of emeraldine-based polyaniline (PANi), and tetracyanoquinodimethane (TCNQ). It was created in 2004 at the University of Durham by Pakistan born scientist Naveed A. Zaidi and colleagues, and it was the first magnetic polymer to function at room temperature. PANi is a conductive polymer that is stable in air. When combined with the free radical -forming TCNQ as an acceptor molecule, it can mimic the mechanism of metallic magnets. The magnetic properties arise from the fully pi-conjugated nitrogen -containing backbone combined with molecular charge transfer side groups. These properties cause the molecule to have a high density of localized spins that can give rise to coupling of their magnetic fields. When this polymer magnet is synthesized, the polymer chains need 3 months to line up before displaying any notable magnetism.
