Iodination of bodipy
Web24 mei 2024 · Bodipy is a popular fluorophore for its large molar absorption coefficient, bright fluorescence, and excellent stability. ... For instance, with iodination, the triplet lifetime of 3,5-distyrylbodipy was significantly reduced from 72 μs to 1.7 μs (Table S2). WebThe preparation, structure, and chemistry of hypervalent iodine compounds are reviewed with emphasis on their synthetic application. Compounds of iodine possess reactivity similar to that of transition metals, but have the advantage of environmental sustainability and efficient utilization of natural resources.

Web12 dec. 2012 · Recently, IOAc was employed as an excellent iodination reagent for the amidation or iodination of aromatic molecules, alkenes, and alkynes. 13 Following these interesting development, we envisioned that IOAc might be a useful iodonium source for the efficient iodination of BODIPY derivatives. Web11 mei 2024 · Absorption properties. The optical properties of BODIPY dyads and triads (concentration of 10 −5 M) were examined in dichloromethane solution using UV–Vis spectrophotometry. The steady-state absorption spectra of D–A and D–A–D have shown in Fig. 2.The photophysical parameters including absorption maxima, molar extinction …
Web27 nov. 2006 · Compounds 22 and 23 are the ‘EVO Blue’ dyes. 38, 39 These have been claimed to be more stable than rhodamine and BODIPY dyes under acidic conditions. ... Direct iodination of Nile Blue is possible, and the 6-iodo derivative 28 can be prepared from this (Scheme 11). WebIodination of the distyryl-extended BODIPY core afforded intersystem crossing quantum yields comparable to 2,6-diiodo-BODIPY. Inclusion of an iodine at the para–meso -phenyl position generally enhanced non-radiative decay in the BODIPY excited-state, leading to lower fluorescence and intersystem crossing quantum yield values.
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 …
