A triptycene-based bis(crown ether) host: complexation with both paraquat derivatives and dibenzylammonium salts

Org Lett. 2006 Mar 16;8(6):1069-72. doi: 10.1021/ol053008s.

Abstract

[reaction: see text] A novel triptycene-based bis(crown ether) host (1) incorporating two dibenzo-24-crown-8 ether moieties has been synthesized. It can form not only a new bis[2]pseudorotaxane with dibenzylammonium salts but also stable clip-shaped complexes with paraquat derivatives. Moreover, the complexation process between 1 and the two classes of guests can be chemically controlled.
