The invention concerns rhodamine derivatives of the general formulae in which Ca-Cd each denote a C atom, and Ca and Cb as well as Cc and Cd are either linked together by a single bond or by a double bond; X1 to X16 denote independently of one another halogen, sulfonic acid, hydrogen or an alkyl residue with 1-20 C atoms in which the alkyl residue can be substituted with one or several halogen or sulfonic acid residues; R1 and R2 are either identical or different and denote either hydrogen, alkyl with 1-20 C atoms, polyoxyhydrocarbyl units, phenyl or phenylalkyl with 1-3 carbon atoms in the alkyl chain in which the alkyl and/or phenyl residues can be substituted by one or several hydroxy, halogen, sulfonic acid, amino, carboxy or alkoxycarbonyl groups where alkoxy can have 1-4 carbon atoms, R1 contains at least one activatable group, R2 and X4 can be optionally linked together via a bridge composed of 0-2 C atoms. In contrast to the prior art, these compounds are characterized in that A1, A2 and A3 can independently of one another denote hydrogen, cyano, halogen and sulfonic acid; B1 denotes either halogen, cyano or hydrogen; B2 denotes hydrogen, amide, halogen and an alkyl residue with 1-20 C atoms. In addition the invention concerns activated rhodamine derivatives, correspondingly conjugated biomolecules and their use in diagnostic systems.
