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 $Cu^2+}$.
一种基于香豆素-噻唑苯并冠醚的新型荧光化学传感器BTC(1)被报道。在乙醇-二甲基亚砜体系中,研究了1与不同碱金属、碱土金属和过渡金属的离子选择性结合特性。BTC(1)对$Hg^2+}$的结合常数高于$Ag^+$、$Pb^2+}$和$Cu^2+}$。
