UNSATURATED DIPYRROMETHENE-BORON BOROCARBONS

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 6 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.
