Chiral and conductive viologen-based supramolecular gels exhibiting tunable charge-transfer properties

Abstract

Robust, transparent, conductive, redox-active and chiral gels are obtained by self-assembly of a cholesterol-substituted 4,4′-bipyridinium. Self-organization gives chiral hollow core–shell cylinders of inner radius 5.2 nm and shell thickness 2.6 nm.
