Anion Dual Mode Fluoro-Chromogenic Chemosensor Based on a BODIPY Core

“…As an extension of the work developed in our research group [7][8][9][10][11], we report a BODIPY derivative bearing a phenyl group at the meso position and a formyl group at position 2 of the BODIPY core for the simultaneous colorimetric and fluorimetric detection of CN − and F − . The recognition behavior of the BODIPY derivative was studied in an aprotic solvent (acetonitrile) in the presence of different anions, and the UV-vis and fluorescence spectroscopic titrations demonstrated a decrease in the absorption band intensity and a fluorescence quenching upon interaction with CN − and F − .…”

Colorimetric Chemosensor for Cu2+ and Fe3+ Based on a meso-Triphenylamine-BODIPY Derivative

“…In continuation of the research developed by our group [27][28][29][30], we present an evaluation of the ion chemosensory ability of a meso-triphenylamine-BODIPY 1 in this work (TPA-BODIPY, Figure 1), which was recently synthesized by us [31,32]. The chemosensory ability was investigated by a preliminary study against several cations and anions with biomedical relevance, followed by spectrophotometric titrations, the Job's plot method, and 1 H NMR titrations.…”
