Краткое описание
• Effect of meso -substituents and solvent on the photo- and thermal stability of BODIPY dyes were investigated. • The introduction into the meso -spacer of the groups (CH 2 ) n COOH or (CH 2 ) n COOCH 3 stabilizes the dyes. • The specific solvation of BODIPYs by polar solvents (DMSO) increases the dyes photo-destruction to ∼10 times. • The high photo- and thermal stability of meso -substituted BODIPY makes them promising dyes for practical purposes. In this paper, the effect of meso -substituents nature and solvent properties on the photo- and thermal stability of BODIPYs, was studied. It was found that the replacement of the hydrogen atom in the methine bridge by CH 3 group, carboxylic acid residues (CH 2 ) n COOH or their esters (CH 2 ) n COOCH 3 (where n = 3, 4) significantly increases the photo- and thermal stability of meso -substituted dyes compared to meso -unsubstituted analog that is in good agreement with the results of NBO analysis. It has been established that the photooxidation process of dyes in solutions proceeds more efficiently in aromatic toluene (in ∼2–3 times) and, especially, in the electron donor DMSO (in ∼10 times) compared to non-polar cyclohexane, which is due to the specific solvation of dye molecules by aromatic and polar solvents.
