Abstract
A simple fluorescent colorimetric chemosensor H2L for rapid detection of Cu 2+ has been developed. The LOD value of H2L towards Cu 2+ was calculated to be 3.8 × 10 −8 M. The interactions between L and Cu 2+ were studied by Job's plot, ESI-MS, DFT calculations and single-crystal structure determination.
