    Synthesis, spectral luminescent properties, and photostability of monoiodo- and dibromo-substituted BF2-dipyrrinates
    摘要:
    4-Iodo-, 4,4'-, and 5,5'-dibromo-substituted BF2-dipyrrinates (BODIPY) have been prepared, and their spectral luminescent properties and photostability have been studied. It has been shown that the introduction of iodine and bromine atoms in the molecule structure results in build-up of the BODIPY phosphorescence and decrease in their fluorescence quantum yield. Basing on the obtained data, the prepared dipyrrinates can be recommended for development of fluorescent sensors for medical and technical applications.

    4,4‐Difluoro‐4‐bora‐3a,4a‐diaza‐s‐indacene (BODIPY) derivatives bearing varied substituents at the meso position (i.e., CF3, CH3, COOR, CHO, CN, Cl, iPr) were synthesized to elucidate the structure–property relationships that give rise to emissive J‐aggregates. Several new BODIPY derivatives can be added to the previously reported 1,3,5,7‐tetramethyl‐8‐trifluoromethyl derivative to the list of those

    Hexamethyl-substituted dipyrromethene had high selectivity towards Zn2+ ions over many environmentally relevant ions, and high sensitivity with the detection limit in nanomolar level (4·10–8 mol/L). In terms of the thermodynamic constant and the fluorescence response of the complexation reaction of [ZnL2], as well as the detection limit of Zn2+ ions, dipyrromethene HL2 surpasses many Zn2+ sensors known in the

    characterization was performed for the homoleptic zinc(II) chelates with dipyrrins containing four methyl or aryl substituents in the pyrrole rings and methine group or nitrogen atom as meso-spacer. It was shown that zinc dipyrrinates with substituted pyrrole rings and a methene spacer exhibited an intense fluorescence in nonpolar media. The phenyl-substituted complex had an order of magnitude stronger fluorescence

    The spectral-fluorescent properties of alkyl-substituted BODIPYs 1–5 in organic solvents were investigated. The alkyl-substituted BODIPYs 1–5 exhibit intense chromophoric properties (lgε = 4.60–5.00). Relative fluorescence quantum yield of studied compounds reaches 66–100% and weakly dependent on the structural and solvation effects.
