| Resumo: | A 4,4-difluoro-4-bora-3<i>a</i>,4<i>a</i>-diaza-<i>s</i>-indacene (BODIPY) derivative functionalized with a formyl group at position 2 was synthesized in 57% yield. The compound was characterized by <sup>1</sup>H and <sup>13</sup>C Nuclear Magnetic Resonance (NMR) spectroscopy and mass spectrometry. The photophysical characterization was carried out by means of absorption and fluorescence spectroscopies in acetonitrile solutions. The BODIPY derivative showed an absorption band at 492 nm and an emission band at 506 nm. A preliminary evaluation of the recognition ability of the BODIPY derivative was investigated in the presence of several cations with environmental and biomedical relevance. A highly selective colorimetric response was obtained for Fe<sup>3+</sup>. |
