Fluorescence Sensing Properties of Thiazolobenzo-crown Ether Incorporating Coumarin

摘要

A new coumarin-thiazolobenzo-crown ether based fluorogenic chemosensor BTC (1) was reported. The ion-selective binding properties of 1 with different alkali, alkaline earth metals and transitional metals were investigated in an ethanol-DMSO system. BTC (1) showed the highest binding constant toward Hg~(2+) over Ag~+, Pb~(2+) and Cu~(2+).
