Abstract

U.v. and n.m.r. spectroscopic investigations in solution have been employed to assess the ability of a series (n = 7-12) of bisparaphenylene-(3n + 4)-crown-n ethers to form stable 1:1 complexes with [Diquat]2+ and [Paraquat]2+ dications; these mappings of molecular recognition are supported by fast atom bombardment mass spectrometry of the 1:1 complexes with both [Diquat][PF6]2 and [Paraquat][PF6] 2, and a single crystal X-ray structure analysis of [Diquat·BPP31C9][PF6]2.
