| Abstract: | reaction: see text] A novel triptycene-based cylindrical macrotricyclic polyether containing two dibenzo24]crown-8 cavities has been synthesized and proved to be a highly efficient host for the complexation with paraquat derivatives. Consequently, a new kind of very stable pseudorotaxane-type complex was formed in solution and in the solid state. |
