Abstract: 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, R1 to R7 permitting the modification of the compound properties (fluorescence emission wavelength, quantitative fluorescent yield), at least one of the substituents S1 and S2 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.
