Novel Furochromenone based Dual Channel Sensors for Selective Detection of Cu2+ with Potential Applications in Sample Monitoring, Membrane Sensing and Photo-printing

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 Cu2+ in solution phase with high association constants [1.27 x 10(4) M-1 (FC1) and 1.05 x 10(4) M-1 (FC2)] and low detection limits [2.88 x 10(-7)M (FC1) and 2.87 x 10(-7) M (FC2)]. Both the molecular systems were also selective for cupric ion in voltammetric and membrane base studies.
