Influence of structural and solvation factors on the spectral-fluorescent properties of alkyl-substituted BODIPYs in solutions. | LitMetric
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. Introduction of methyl, propyl, amyl and heptyl substituents in the 2,6-positions of the pyrroles the results in a significant red shift (22-29nm) in the electronic absorption and fluorescence spectra.
