Abstract
We report the design and synthesis of a novel styrylbenzothiazolium (3) derivative developed as a fluorescent and colorimetric chemodosimeter with high selectivity toward Hg2+, CN− and OH− ions. An obvious loss of pink color in the presence of Hg2+ and CN− ions could make it a suitable “naked eye” indicator. We propose a sensing mechanism whereby the benzenoid form is changed to a quinoid form upon Hg2+ binding in a 1:1 stoichiometric ratio. More significantly, the styrylbenzothiazolium-Hg2+ and styrylbenzothiazolium-CN− complexes exhibited a dual-channel chromo-fluorogenic response. The sensors exhibit remarkable Hg2+-, CN−-, and OH−-selective red fluorescence but remain dark-green in the presence of a wide range of tested metal ions and anions.
