ANION RECOGNITION BY NEW ACYCLIC QUATERNARY POLYBIPYRIDINIUM RECEPTORS
New acyclic quaternary polybipyridinium receptors L1-L 4 containing 5,5′ - and 4,4′ -disubstituted-N,N′- dimethyl-2,2′ -bipyridinium are prepared and shown by preliminary 1H and 13C NMR titration investigations to coordinate chloride and bromide anionic guest species.
