Novel Triptycene-Based Cylindrical Macrotricyclic Host:Synthesis and Complexation with Paraquat Derivatives

摘要

A novel triptycene-based cylindrical macrotricyclic polyether containing two dibenzo[24]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.
