Abstract

A cage-type receptor binds an NH₄⁺ ion by cation-π interactions and hydrogen bonding with high sensitivity and selectivity, comparable or even superior to those of the natural antibiotic nonactin over a wide pH range. The high performance, low cost, and easy synthesis may offer practical applications for this receptor as an ammonium ion sensor.

Keywords: ammonium ion; hydrogen bonds; molecular recognition; pi interactions; supramolecular chemistry.
