摘要 |
The invention relates to unsaturated dipyrromethene-boron borocarbons of formula (I) and the use thereof for fluorescence or electroluminescent analysis. The fluorescent properties are provided by the central ring of six atoms comprising the -N-B-N- sequence, R<SUP>1 </SUP>to R<SUP>7 </SUP>permitting the modification of the compound properties (fluorescence emission wavelength, quantitative fluorescent yield), at least one of the substituents S<SUP>1 </SUP>and S<SUP>2 </SUP>has a chromophore end group which permits an excitation of the molecule at wavelengths close to those of the substituent chromophore. A preferably selected from the chromophore substituents with a wavelength close to the ultraviolet which significantly increases the Stokes displacement.
