Abstract

A new chemodosimeter 2-((E)-(((E)-anthracen-9-ylmethylene)hydrazono)methyl)-5-(diethylamino)phenol (HA-DAS) has been synthesized for the detection of hypochlorite. HA-DAS showed a selective turn-off fluorescence for ClO⁻ through oxidation reaction between imine bond and oxidizer ClO⁻. It also could detect ClO⁻ over various competitive anions including ROS (reactive oxygen species). The photophysical properties and sensing mechanism of HA-DAS toward ClO⁻ were studied by UV-vis and fluorescent spectroscopy, NMR titration, ESI-MS and DFT calculations.
