Self-complementary azolophanes

Abstract

By incorporating a m-terphenyl spacer, azolophanes containing imidazole, benzimidazole or benzotriazole and 2, 5-dimethoxy-1,4-xylyl subunits were synthesised by N-alkylation followed by quarternisation. The electrochemical parameters obtained for the azolophanes indicated that the redox processes are quasireversible.
