Unveiling the highly selective time-dependent colorimetric response of 8-hydroxyquinoline and indolinium-conjugated donor-π-acceptor (D-π-A) hybrid for the detection of copper(II) ions

GPG. Durga PrasadTSTadepalli SanjeevakumarVRVenkatachalam Rajeshkumar

Key Points

  • The aim is to develop a chemosensor that selectively detects copper(II) ions using colorimetric changes over time.
  • Synthesis of indolinium-8-hydroxyquinoline-based D-π-A hybrid chemosensor.
  • Systematic investigation of the time-dependent colorimetric response.
  • Assessment of selectivity for Cu2+ ions.
  • The chemosensor shows a distinct color change when exposed to Cu2+ ions.
  • The response is highly selective and time-dependent.
  • Effectiveness in differentiating copper ions from other metal ions.

Abstract

A novel indolinium-8-hydroxyquinoline-based donor-π-acceptor colorimetric chemosensor, IQS, was synthesized and systematically investigated time-dependent colorimetric response for the selective detection of Cu 2+ ions. The probe exhibited a distinct, time-dependent color...
