In this study, we present the synthesis of 2-(((2-aminoethyl)imino)methyl)phenol (HL1) and the iron (III) complex (Fe(L1)Br, ()), confirmed by X-ray diffraction analysis. The absorption and emission properties of complex were assessed in the presence and absence of different physiologically relevant analytes, finding a fluorescent turn-on when OH was added.
