Two furochromenone based molecular systems ( FC1 and FC2 ) were synthesized by a microwave assisted three component reaction and investigated for their metal sensing abilities. Reported chemosensors displayed a selective turn off fluorescence response in the presence of Cu 2+ in solution phase with high association constants [1.27×10 4 M –1 ( FC1 ) and 1.05×10 4 M –1 ( FC2 )] and low detection limits [2.88 × 10 −7 M ( FC1 ) and 2.87 × 10 −7 M ( FC2 )]. Both the molecular systems were also selective for cupric ion in voltammetric and membrane base studies.
