Abstract

Abstract Three tricarbocyanine dyes (IR-897, IR-877, and IR-925) with different thiourea substituents that function as dosimeter units through specific Hg 2+-induced desulfurization have been demonstrated in a fast indicator paper for Hg 2+ and MeHg+ ions. In comparison with available Hg 2+-selective chemodosimeters, IR-897 and IR-877 show several advantages, such as convenient synthesis, very long wavelengths falling in the near- ...
