Conducting polymers consisting of a polycation, 7,7,8,8‐tetracyanoquinodimethan anions (TCNQ−) and neutral TCNQ are described. Polycations employed were derived from poly‐4‐vinylpyridine, atactic and isotactic poly‐2‐vinylpyridine, poly‐N‐vinyl‐imidazole, polyethyleneimine, poly‐4‐dimethylaminostyrene, and a copolymer of 4‐vinyl‐pyridine and styrene. These materials have an unusual combination of properties, not reported before for organic semiconductors, in that they are of high molecular weight, are soluble in organic solvents, and have conductivity controllable over several orders of magnitude by varying their content of neutral TCNQ. The highest conductivity observed so far for these materials is 10−3 Ω−1 cm.−1. In the solid‐state conduction proceeds through an electronic mechanism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
