    摘要: The present invention provides low molecular weight fluorescent labeling complexes with large wavelength shifts between absorption of one dye in the complex and emission from another dye in the complex. These complexes can be used, for example, for multiparameter fluorescence cell analysis using a single excitation wavelength. The low molecular weight of the complex permits materials labeled with the complex to penetrate cell structures for use as probes. The labeling complexes are synthesized by covalently attaching through linkers at least one cyanine fluorochrome to another low molecular weight fluorochrome to form energy donor-acceptor complexes. Resonance energy transfer from an excited donor to fluorescent acceptor provides wavelength shifts up to 300 nm. The fluorescent labeling complexes preferably contain reactive groups for the labeling of functional groups on target compounds, such as derivatized oxy and deoxy polynucleic acids, antibodies, enzymes, proteins and other materials. The complexes may also contain functional groups permitting covalent reaction with materials containing reactive groups.

    摘要: Triaryl-methane dyestuffs which are free from sulfonic acid and carboxylic acid groups and are selected from the group consisting of dyestuffs having one of the following four formulae: ##STR1## wherein R is alkyl, aralkyl, cycloalkyl or aryl; R.sub.1 is hydrogen, alkyl, aralkyl or cycloalkyl; R.sub.2 is alkyl, aralkyl, cycloalkyl or aryl; R.sub.1 and R.sub.2 additionally including divalent alkylene when joined together with the nitrogen or with a carbon atom in the o-position in the ring A to form a heterocyclic ring; R.sub.3 is hydrogen, alkyl, aralkyl, aryl, aralkoxy, aryloxy, halogen, carboxylic acid ester radical, carbonamido, sulfonamido, cyano, nitro, alkylsulfonyl, aryalkylsulfonyl, arylsulfonyl or acyl; and X is the radical of an anion; ##STR2## wherein R is alkyl or cycloalkyl; R.sub.1 is hydrogen, alkyl, aralkyl, cycloalkyl or aryl; R.sub.2 is alkyl, cycloalkyl, aralkyl or aryl, halogen or cyano; R.sub.1 and R.sub.2 additionally include divalent alkylene when joined together with the nitrogen atom or with a carbon atom in the o-position in the ring A to form a heterocyclic ring; R.sub.3 is hydrogen or alkyl; R.sub.4 is alkyl or cycloalkyl; and X is the radical of an anion; ##STR3## wherein R is alkyl or cycloalkyl; R.sub.1 is hydrogen or methyl; R.sub.2 is methyl, aryl, or cycloalkyl; R.sub.3 is hydrogen or alkyl; R.sub.4 is alkyl or cycloalkyl; R.sub.3 and R.sub.4 additionally include divalent alkylene when joined together to form a carbocyclic ring; and X is the radical of an anion; and ##STR4## wherein at least one R is halogen, alkyl, or alkoxy and the other R's are hydrogen, halogen, alkyl, or alkoxy; R.sub.1 is hydrogen or methyl; R.sub.2 is methyl, aryl, or cycloalkyl; and X is the radical of an anion.Process of preparing the above dyestuffs by condensation of an appropriate benzophenone with an aromatic amine or by the oxidation of the corresponding leuco compound. These dyestuffs are particularly useful in dyeing or printing materials made of polymers of acrylonitrile, polymers of as.-dicyanoethylene, and acid-modified aromatic polyesters.
