Ionenes with imidazole and benzimidazole nuclei in a polycation chain and polymeric ion-radical salts of 7,7,8,8-tetracyanoquino-dimethane on their basis

Abstract

Polycationic polymers - ionenes— were synthesized by the Menshutkin reaction from p-xylylene-1,1′-diimidazole, p-xylylene-1,1′-bis-benzimidazole, pentamethylene-1,1′-bis-benzimidazole, and organic dihalogenides: p-xylylenedibromide, 1,5-dibromopentane, and 1,4-dibromobutane. They served for the preparation of polymeric ion-radical salts of 7,7,8,8-tetracyanoquinodimethane. The minimum values of specific resistivity of the polycationic salts were found to lie between 29 and 109 Ω cm. The thermal stability of the salts was investigated.
