CA 2748544

The invention relates to fluorescent hydrophilic compounds according to the following formula (I) in which: S1 is a group of formula -C?C-L'-A, where L' is a linkage group and A is a polar functional group; S2 is a group -C?C-L'-A, identical to or different from S1; -F; -H; or a hydrocarbon chain, possibly interrupted by one or more oxygen atoms, and to the use thereof, in particular in aqueous or hydrophilic media.

L'invention concerne des composés fluorescents et hydrophiles répondant à la formule (I) suivante dans laquelle : * S1 représente un groupe de formule -C-7C-L'-A où L' est un groupement de liaison et A est un groupement fonctionnel polaire; * S2 représente un groupe -C~C-L'-A identique ou différent de S1; -F; -H; ou une chaîne hydrocarbonée, éventuellement interrompue par un ou plusieurs atomes d'oxygène, et leur utilisation, notamment dans des milieux aqueux ou hydrophiles.
