Hybrid polyurethane–MOF platform for turn-on fluorescent sensing of Cu 2+ ion

SSSusan SarvarianMLMoslem Mansour LakourajRNRafieh-Sadat Norouzian

Key Points

  • The aim is to develop a hybrid nanocomposite for sensitive detection of Cu2+ ions through fluorescence.
  • Created a nanocomposite foam using polyurethane and MOF UIO-66-NH.
  • Examined fluorescence properties and responses at pH 5.
  • Illustrated the sensing mechanism of the developed composite.
  • The nanocomposite exhibited strong fluorescence with tunable properties.
  • Distinct optical responses were noted specifically for copper ions.

Abstract

Illustration of the sensing mechanism of the PUF/UIO-66-NH–calcein nanocomposite. The hybrid nanocomposite foam exhibits strong, tunable fluorescence and possesses distinct optical responses to copper ions at pH 5.
