| Abstract |
A new molecular cage was synthesized containing both hydrogen bonding donors such as amides and pyrroles and hydrogen bonding acceptors of imines. It was proved by 1H NMR and UV/Vis spectroscopic analyses that this three dimensional receptor is able to bind oxoanions such as dihydrogen phosphate, pyrophosphtate, hydrogen sulfate, and sulfate (as their tetrabutylammonium salts) with high selectivity and affinity relative to other anions including halide anions. The single crystal X-ray diffraction analysis showed that the receptor forms a 1;1 complex with the dihydrogen phosphate where the two hydrogen atoms of the anion forms hydrogen bonds with the nitrogen atoms of imine of the cage with the amide and pyrrolic NH being hydrogen-bonded to the oxygen atoms of the anion. |
