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.
