A multistate chiroptical macromolecular switch based on the redox behavior of tetrathiafulvalene (TTF) units has been prepared from a chiral TTF functionalized with an isocyanide group. Polymerization takes place diastereoselectively due to an unusually long-range chiral induction, yielding a helical backbone with organized electroactive side groups (see Figure). This organized redox system may lead to applications in molecular devices.
