| Abstract |
A new tripodal ion receptor comprised of three pyridine groups and indole amide groups was synthesized. The receptor was found to bind cations with the pyridine constituents and anions with the indole and amide groups via hydrogen bonding interactions. In addition, the receptor proved capable of recognizing specific ion pairs, for example, LiCl. Upon the exposure of the receptor to anions, it displayed colorimetric responses to F-, HCO3-, H2PO4-, and HP2O73- accompanying bathochromic shifts of its absorption band. These findings were taken as evidence for hydrogen bonding interactions between the receptor and such anions. On the other hand, the receptor was found to form complexes with certain cations such as Zn2+ and Li+. It was also revealed by 1H NMR and UV spectroscopic analyses that the receptor was able to bind lithium chloride highly selectively over other akali metal chloride salts. |
