Abstract

Anion Recognition by New Acyclic Quaternary PolybipyridiniumReceptors. -Alkylation of the diamine (II) with the bromomethylmethylbipyridine (I) yields the bipyridyl-disubstituted diamine (III) which is converted into the quaternary receptor (VI) by methylation and treatment with ammonium hexafluorophosphate. Three similar polybipyridinium hexafluorophosphates are also synthesized. The receptors coordinate chloride and bromide guest anions. -(BEER, P. D.; WHEELER, J. W.; GRIEVE, A.; MOORE, C.; WEAR, T.;
