Abstract

La présente invention concerne des colorants fluorescents de la formule (I), ainsi que les tautomères de valence de ceux-ci. Dans cette formule, Q représente une fraction conjuguée augmentant le rendement quantique fluorescent du composé; R1 représente un groupe fonctionnalisé de la formule -(CH2)jY, où Y est choisi dans le groupe constitué par SO3H, COOH, NH2, CHO, NCS, époxy, phtalimido, et COOZ où Z représente un groupe partant; R2 représente un groupe fonctionnalisé de la formule -(CH2)kY' où Y' est choisi dans le groupe constitué par SO3H, COOH, NH2, CHO, NCS, époxy, phtalimido et COOZ où Z représente un groupe partant; M<+> représente un contre-ion choisi dans le groupe constitué par ammonium, des cations de métaux alcalins, et des cations de métaux alcalino-terreux; n = 1 à 4; m = 1 à 4; J = 2 à 10 et k = 2 à 10.
