Abstract

A new thiacalix[4]arene-cinnamaldehyde derivative 3, which undergoes red shift in the fluorescence spectrum in the presence of Ag⁺ ions, has been synthesized. This emission shift is attributed to the intramolecular charge transfer process in the presence of Ag⁺ ions with a detection limit in the nanomolar range.
