Abstract
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 [1.27×104 M–1 (FC1) and 1.05×104 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.
