Web13 jan. 2024 · A new BODIPY derivative (o-I–BDP) containing an iodine atom in the ortho position of the meso-linked phenyl group was prepared. Photophysical and electrochemical properties of the molecule were compared to previously reported iodo BODIPY derivatives, as well as to the non-iodinated analog. Web14 okt. 2015 · Boron dipyrromethene (Bodipy) is one of the most extensively investigated organic chromophores. Most of the investigations are focused on the singlet excited state of Bodipy, such as fluorescence. In stark contrast, the study of the triplet excited state of Bodipy is limited, but it is an emerging area, since the triplet state of ...

WebA theoretical and experimental study on the iodination of BODIPY dyes with different degrees of substitution has been developed. Polyhalogenated BODIPYs synthesized in this work are the first examples of this type of dyes with more than two halogen atoms in the BODIPY core and they can be selectively functionalized.
WebThe present study is devoted to the combined experimental and theoretical description of the photophysical properties and photodegradation of the new boron-dipyrromethene (BODIPY) derivatives obtained recently for biomedical applications, such as bacteria photoinactivation (Piskorz et al., Dyes and Pigments 2024, 178, 108322). Absorption and … WebLi et al. reported a RNA-targeted BODIPY 14 as a new FMR to detect intracellular viscosity (Figure 2C; Li et al., 2016).FMR 14 showed two different maximum wavelengths at 496 and 565 nm, respectively. Similar to most fluorescent ratiometry probes, fluorescence measurements of BODIPY 14 showed two different emitted wavelengths (496 and 565 …
WebBODIPY, short for boron dipyrrole methylene, is an organic single and double bond compound of interest as a fluorescent dye. BODIPY consists of dipyrrole methylene complexed with a disubstituted boron center (usually BF2). The IUPAC name of the BODIPY core is 4,4-difluoro-4-boron 3a, 4a-diaza-s-indenotetraene.
