Iodination of bodipy
WebThe following step is iodination to add iodine atoms to the BODIPY core; this modification is described to promote singlet oxygen generation in the final compound. The step after iodination adds two equivalents of p -tolualdehyde to the scaffold through Knoevenagel condensation to extend the conjugation of the final compound 3 with a yield of 49%. WebSynthesis of conjugatable BODIPY fluorophores. Access to water-soluble carbohydrate-BODIPY hybrids. At the beginning of our studies, only a few examples on the preparation of carbohydrate-BODIPY hybrids existed in the literature, [], and a key factor to the success on the investigations compiled in this manuscript was the launching of a collaboration with …

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. Web15 okt. 2024 · The probe BODIPY 140 displayed a remarkable selective colorimetric and turn-on fluorometric responses (up to 25-fold) with the detection limit of 0.26 μM. The BODIPY 140 could be applied for reactive oxygen species (ROS) detection in biological cells for both exogenously added hypochlorite as well as endogenously generated ROS.

Web18 feb. 2011 · Direct, oxidizer-free substitution of the 3-hydrogen of BODIPY derivatives has been established through a vicarious nucleophilic substitution procedure. This methodology has been combined with a reversible Michael addition on nitrostyrenes to provide a novel, highly efficient entry to the valuable 3-styrylated BODIPY dyes. 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 …
