| Özet |
| A novel π-conjugated fluorescent compound, herein referred to as BisThio-BDPY, incorporating a central thiophene ring substituted at the 3- and 4-positions with para-BODIPY-functionalized phenyl groups was synthesized and fully characterized. The compound exhibited strong absorption and fluorescence attributed to BODIPY units, with photophysical properties evaluated across various solvents. Selective and sensitive fluorescence quenching by Fe3+ ions was demonstrated, outperforming a broad spectrum of competing metal ions. Fluorescence titration showed a linear response between 10 and 60 μM Fe3+, with a detection limit of 0.40 μM, below international permissible levels for drinking water. Job's plot analysis confirmed a 1:1 stoichiometric interaction between the probe and Fe3+. These results highlight the probe's potential for environmental Fe3+ monitoring and bioimaging applications. |
