Iodination of bodipy
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 ... 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.

Web14 okt. 2024 · For instance, the optical properties of BODIPY dyes are inherently related to the degree of aggregation and the mutual orientation of BODIPY units within these aggregates. Whereas the noncovalent aggregation of various BODIPY dyes has been studied in diverse media, the ill-defined nature of these aggregates has made it difficult … WebIodination Reagents for Proteins. Iodination involves the introduction of radioactive iodine into certain amino acids (usually tyrosines) in proteins and peptides. Iodination takes place at the positions orthogonal to the hydroxyl group on tyrosine; mono- or di-substitution can occur. When iodinatable sites such as tyrosines are absent or of ...
