BODIPY dyes are unique fluorophores that can be used in numerous application areas because of their interesting photophysical properties such as high molar absorptivity, tunable absorption and emission energies, and high fluorescence quantum yields. They show impressive photophysical property changes upon substitution of functional groups on the main core structure. Exchange of the meso-carbon on dipyrrin core with nitrogen produces an analog class of BODIPY called aza-BODIPY. Up to now, various kinds of BODIPY and aza-BODIPY derivatives have been developed and applied in science and industry. In this chapter, recent studies on photophysical properties of BODIPY derivatives are summarized.

“…The limit of detection (LOD) of copper ion was calculated as 5.4×10 −7 M by using the fluorescence intensities of t -BODIPY in Figure 6 . When the result is compared with our previous paper concluding yeast cell studies, it can be evaluated as a worse value [ 29 ]. However, this LOD value can be accepted based on the U.S.’s defined contaminant level in tap water, which is 20 μM, for copper ions; hence, the probe, t -BODIPY , is effective for the recognition of copper (II) in real samples.…”

A general synthetic method was improved to synthesize a chemosensor based on a tripodal Bodipy (t-BODIPY) structure. The product and its intermediates products were successfully prepared and fully characterized. The metal ion sensing performance of the tripodal compound was evaluated by. UV/Vis and fluorescence spectroscopies. According to the obtained data, t-BODIPY is a selective and. sensitive fluorescence probe for detection of Cu 2+ ions. in the presence and in the absence of competing ions. This chemosensor presents relatively a low detection limit of 5.4 x10 -7 M for Cu 2+ . Bio-imaging studies on living yeast cells suggest that t-BODIPY has some advantages over other chemosensors to recognize copper (II) ions.

“…Furthermore, the core of BODIPY can be functionalized in order to improve its photophysical properties for its intended applications [ 20 , 21 ]. Although several chemosensors based on a BODIPY core have been reported for the detection of Cu 2+ and Fe 3+ , these sensors detect these cations separately [ 22 , 23 , 24 ]. Most of these chemosensors also display a fluorimetric response which requires specialized equipment for the visualization of the results.…”

Optical chemosensors are a practical tool for the detection and quantification of important analytes in biological and environmental fields, such as Cu2+ and Fe3+. To the best of our knowledge, a BODIPY derivative capable of detecting Cu2+ and Fe3+ simultaneously through a colorimetric response has not yet been described in the literature. In this work, a meso-triphenylamine-BODIPY derivative is reported for the highly selective detection of Cu2+ and Fe3+. In the preliminary chemosensing study, this compound showed a significant color change from yellow to blue–green in the presence of Cu2+ and Fe3+. With only one equivalent of cation, a change in the absorption band of the compound and the appearance of a new band around 700 nm were observed. Furthermore, only 10 equivalents of Cu2+/Fe3+ were needed to reach the absorption plateau in the UV-visible titrations. Compound 1 showed excellent sensitivity toward Cu2+ and Fe3+ detection, with LODs of 0.63 µM and 1.06 µM, respectively. The binding constant calculation indicated a strong complexation between compound 1 and Cu2+/Fe3+ ions. The 1H and 19F NMR titrations showed that an increasing concentration of cations induced a broadening and shifting of the aromatic region peaks, as well as the disappearance of the original fluorine peaks of the BODIPY core, which suggests that the ligand–metal (1:2) interaction may occur through the triphenylamino group and the BODIPY core.
