We report an efficient and convenient method for preparing nitro-3-carboxamide coumarin derivatives, proposed as novel fluorescent chemosensor, through microwave irradiation. This compound can be used as fluorescent probe for Cu(2+) with selectivity over other metal ions in aqueous solution. The fluorescence of 6-nitro-N-[2-(dimethylamino)ethyl]-2-oxo-2H-chromene-3-carboxamide(3) is the highest in the presence of Cu(2+), with stronger excitation at λ=320nm than for the other cations tested.
我们报道了一种通过微波辐射制备硝基-3-羧酰胺香豆素衍生物的高效便捷方法，这种衍生物被提议用作新型荧光化学传感器。该化合物可作为水溶液中对Cu(2+)具有选择性的荧光探针，优于其他金属离子。6-硝基-N-[2-(二甲氨基)乙基]-2-氧代-2H-色烯-3-羧酰胺(3)在Cu(2+)存在下荧光最强，在λ=320nm处的激发比其他测试阳离子更强。
