A new highly selective, reversible, chromogenic, and fluorogenic chemosensor (4) based on thiazole–coumarin moieties for quantification of copper ions in aqueous-DMSO was designed and synthesized. The mechanism of fluorescence was based on ICT, which was modified by the introduction of an electron-donating diethylamino group making it chromogenic and increasing the binding affinity. The selectivity
设计并合成了一种基于噻唑-香豆素部分的新型高选择性,可逆,发色和荧光化学传感器(4),用于定量DMSO水溶液中的铜离子。荧光的机理是基于ICT的,它通过引入给电子的二乙氨基基团进行了修饰,使其发色并增加了结合亲和力。对铜离子的选择性不受代表性碱金属,碱土金属或其他过渡金属的存在的影响。
