Abstract
The new ditopic receptors 1-3 (Figure 1) have been synthesized and their bi nding ability for alkaline and transition metal cations has ben investigate d by halide and W-Vis titrations. The recognition of complementary molecule s through hydrogen bonding has been studied by H-1-NMR. The simultaneous re cognition of these two guests is an anti-cooperative event.
