Iodination of bodipy
Web8 feb. 2013 · As a trial reaction, we attempted a mechanochemical synthesis of BODIPY dye 1 with commonly used reagents. The condensation of 2,4-dimethylpyrrole and 4-nitrobenzaldehyde was performed with grinding by using a simple mortar and pestle, followed by the addition of a few drops of TFA (complete consumption of the aldehyde … WebBODIPY dyes are therefore often the preferred choice for labeling nucleotides, amino acids and other low molecular weight ligands. BODIPY dye conjugates of low molecular weight molecules also tend to be more permeant to live cells than are conjugates of charged fluorophores (Membrane-Permeant Reactive Tracers—Section 14.2).

WebCapturing volatile radionuclide iodine from nuclear and medical waste streams is an important environmental issue. In this work, we found that the 2,6-position hydrogen atoms of a BODIPY core undergo fast iodination with volatile iodine at room temperature. Inspired by our observation, two novel BODIPY-based conjugated porous polymers (CPPs) BDP … WebAbstract. Photodynamic therapy (PDT) has shown promise as an effective treatment modality for cancers and other localized diseases, such as age-related macular degeneration and actinic keratosis. PDT relies on light, photosensitizer and oxygen as elements in its mechanism of action.
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. Web12 dec. 2012 · A practical, convenient, and highly efficient mono- and diiodination of 1,3,5,7-tetramethyl BODIPY derivatives was achieved by using IOAc as the iodination reagent which was generated in situ from the mixture of phenyliodine (III) diactate with iodine. The iodinated reactions were performed smoothly to give the mono- or …
WebPhotodynamic therapy (PDT) is a promising noninvasive treatment that has drawn great attention.
