摘要
The pseudorotaxane formed in CH2Cl2 solution by (9-anthrylmethyl)methylammonium hexafluorophosphate salt and dibenzo-24-crown-8 can be unthreaded by addition of NBu4Cl through the formation of a strong ammonium chloride ion pair, while pseudorotaxane rethreading can be performed by addition of NHBu3PF6; all these processes can be followed by pronounced changes in the luminescence spectra, which could allow the use of this system as a fluorescent sensor for chloride ions.
