Doubly Encircled and Double‐Stranded Pseudorotaxanes

Abstract

Novel supramolecular architectures formed by self-assembly of three or four charged and neutral species have been prepared and characterized. In both the solution and solid states the two dibenzylammonium ions in the dicationic 1:2 complex 1 are threaded simultaneously through bis-para-phenylene[34]crown-10. This macrocyclic polyether forms a 2:2 complex with α,α′-bis(benzylammonium)-para-xylylene bis(hexafluorophosphate) in the solid state.
