摘要：

New acyclic quaternary polybipyridinium receptors containing 5,5'- and 4,4'-disubstituted N,N'-dimethyl-2,2'-bipyridinium moieties (L(1)-L(6))and a polypyridinium receptor L(7) have been synthesised, H-1 NMR titration studies in deuteriated DMSO show these receptors complex chloride and bromide anions, with a 1 : 1 stoichiometric ligand:chloride stability constant evaluations suggesting the amide containing polypyridinium receptor (L(7)) forms the most thermodynamically stable chloride anion complex, Square-wave voltammetric investigations showed some of the polypyridinium receptors to recognise electrochemically the chloride anion.
