A compound is provided which has dual emission properties and which is useful in light devices, and which has formula (I):  represents a condensed bicyclic aromatic radical comprising from 6 to 22 carbon atoms, and from 1 to 3 heteroatom(s) selected from the group consisting of: N, S and O; radical.

Molecules presenting dual emission properties

The invention relates to novel fluorescent compounds derived from non-fluorinated dipyrromethene-boron, to a method for preparing same and to the use thereof for the fluorescent marking of biological molecules. The invention also relates to biological molecules marked with said fluorescent compounds, and to the use thereof in detection methods such as medical diagnosis methods. More particularly, the detection methods of the invention are particularly useful for diagnosing neurodegenerative diseases such as Alzheimer's disease.

Fluorescent boron-substituted dipyrromethenes and use thereof for diagnosis

Dipyrromethene-boron hydrophilic fluorescent compounds The invention concerns fluorescent and hydrophilic compounds meeting following formula (I): wherein:

Dipyrromethene-boron hydrophilic fluorescent compounds

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 &#x2014;N&#x2014;B&#x2014;N&#x2014; sequence, Rto Rpermitting the modification of the compound properties (fluorescence emission wavelength, quantitative fluorescent yield), at least one of the substituents Sand Shas 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.
