A Colorimetric and Fluorescent Sensor Based on Novel Iminocoumarin Precursor for Pd(2+) Dectection in Aqueous Solution

Lianqing Li et al. J Fluoresc. 2015 Sep.

Abstract

A novel iminocoumarin precursor L was designed and well characterized. Sensor L showed high selectivity toward Pd(2+) in aqueous solution (CH3CN:H2O, v/v, 1:1) with a detection limit is 2.1 × 10(-7)M. Iminocoumarin was formed when added Pd(2+) to the solution of L by removing the propargylic group.

Keywords: Colorimetric sensor; Fluorescent sensor; Palladium detection.
