title: Synthesis and Properties of a Novel FRET-Based Ratiometric Fluorescent Sensor for Cu(2.).
abstract: A novel FRET-based probe LS3 was designed and synthesized. As expected, it exhibited high selectivity and sensitivity for detecting Cu(2+) over other commonly coexistent metal ions. The detection limit was measured to be 0.0423 μM for Cu(2+), which can meet the selective requirements for practical application. In addition, the newly synthesized compound 3a/b have potential value of further synthesizing more analogous FRET-based probes.
