Selective binding of hydrogen chloride and its trapping through supramolecular gelation

摘要

A pyridine containing amino acid based gelator forms get in aqueous media in the presence of hydrochloric acid and the chloride ion is found to be very selective for gelation. The gelator is successfully applied for the detection and trapping of hydrogen chloride gas and this indicates its probable application for removing hazardous HCl gas from the environment.
