Complexation between triptycene-based macrotricyclic host and π-extended viologens: formation of supramolecular poly[3]pseudorotaxanes†
Abstract
Triptycene-based macrotricyclic host containing two dibenzo-30-crown-10 moieties could form ladder-like supramolecular poly[3]pseudorotaxanes with π-extended viologens in both high concentration solution and solid state.
