Oxacalixarenepyrazine and functional polyether derived oxacalixcrown-6, -7, and -8 were synthesized, and their host–guest complexation with paraquat to form pseudorotaxanes was studied. The pseudorotaxanes were then successfully used in the construction of two oxacalixcrown-tetracationic cyclophane [CBPQT<sup>4+</sup>] based catenanes.
