Halide anion recognition by new acyclic quaternary polybipyridinium and polypyridinium receptors
New acyclic quaternary polybipyridinium receptors containing 5,5′- and 4,4′-disubstituted N,N′-dimethyl-2,2′-bipyridinium moieties (L1-L6) and a polypyridinium receptor L 7 have been synthesised. 1H NMR titratlon studies in deuteriated DMSO show these receptors complex chloride and bromide anions, w...
