A new macrocyclic anion receptor utilizing amide, amine, and 9-anthracenyl hydrogens
摘要:
We have developed a new macrocyclic anion receptor 2 utilizing two amide hydrogens, two amine hydrogens and 9-anthracenyl hydrogen to bind anions. As the binding cavity formed from these hydrogens is pre-organized and its size is different from that of the previously reported receptor 1 due to its cyclization, the affinity of the receptor 2 for the anion is somewhat different from that of the receptor 1. The receptor 2 binds anions through hydrogen bonds with a selectivity of H2PO4- > CH3CO2- > F- > C6H5CO2- > Cl- > Br- > l(-) while the receptor 1 binds anions with a selectivity of CH3CO2- > H2PO4- > C6H5CO2- > HSO4- > ClO4- > NO3-.
