Pd. Beer et al., NEW CLASSES OF ANION RECEPTOR-CONTAINING CHARGED AND NEUTRAL TRANSITION-METAL LEWIS ACIDIC RECOGNITION SITES, Journal of the Chemical Society, Chemical Communications, (10), 1993, pp. 828-830
A variety of new classes of anion receptor containing positively charg

cidic binding sites in combination with amide N-H groups have been pre
pared and shown to complex halide anionic guest species.
