‘Organic metals’: a new class of conducting ion-radical salts based on 7,7,8,8-tetracyanoquinodimethane and iodine
Abstract
A new class of conducting ion-radical salts containing parallel chains of TCNQ and I3– is described, all of which possess a 1/3 filled electronic band, show metallic properties at high temperatures, and undergo a metal–insulator transition as the temperature is decreased.
