Herein, a novel fluorescent indicator for the real-time monitoring of amines is described. This probe contains a complex of europium-(thenoyltrifluoroacetone)(3) (Eu(TTA)(3)) that efficiently reacts with primary and secondary amines. The electron-withdrawing trifluoroacetyl undergoes a nucleophilic addition with amines, and the complex was used to selectively detect BuNH(2) and Et(2) NH (quenching concentration for BuNH(2): 10(-4) M, for Et(2)NH: 1.2 × 10(-3) M) by monitoring emission; no… CONTINUE READING
