Abstract

The new ditopic receptors 1–3 (Figure 1) have been synthesized and their binding ability for alkaline and transition metal cations has ben investigated by halide and UV-Vis titrations. The recognition of complementary molecules through hydrogen bonding has been studied by 1H-NMR. The simultaneous recognition of these two guests is an anti-cooperative event.
