Abstract

A highly selective sulphur-containing colorimetric chemosensor APTS ((E)-2-(tert-butyl)-6-(((2-(phenylthio)phenyl)imino)methyl)phenol) was synthesised for detecting Cu²⁺. APTS showed a clear colour change from colourless to yellow with Cu²⁺. The detection limit of APTS for Cu²⁺ was 0.52 μmol/L. APTS could also be used as a test strip for detecting Cu²⁺. To understand the binding mode of APTS with Cu²⁺, ultraviolet-visible spectroscopy and electrospray ionisation-mass spectrometry analyses were conducted. The sensing mechanism of sensor APTS towards Cu²⁺ was proposed to be the combination of intramolecular charge transfer and ligand-to-metal charge-transfer through theoretical calculations.
