Two new coumarin derivatives bearing 2-aminothiazole moiety were synthesized and the molecular structures were confirmed by NMR and HRMS. In acetonitrile, C1 exhibited a selective fluorescence enhancement effect to Mg2+ among the metal ions examined. C2 showed a selective fluorescence quenching effect to Co2+.
合成了两种新型的吡喃香豆素衍生物,带有2-氨基噻唑基团,分子结构通过核磁共振(NMR)和高分辨质谱(HRMS)进行了确认。在乙腈中,C1对所考察的金属离子中Mg2+表现出选择性荧光增强效应。C2则对Co2+表现出选择性荧光淬灭效应。
