ABSTRACT:
Naphthalene-1,4,5,8-tetracarboxylic bisimides of the general formula Iwhere the variables are defined as follows:R1and R2independently of one another are hydrogen, substituted or unsubstituted alkyl or substituted or unsubstituted aryl;X and Y independently of one another are halogen, amino or a radical with the formula —NHR3, —OR3, where R3has the formula —CH2R4, —CHR4R5, or —CR4R5R6, where R4, R5, and R6independently of one another are hydrogen, substituted or unsubstituted alkyl, aryl, alkoxy, alkylthio, aryloxy or arylthio, and at least one of the two substituents X and Y is other than halogen,their preparation and use as fluorescent dyes, for coloring high molecular mass organic materials and inorganic materials, as laser dyes, and also for fluorescence marking and as fluorescent labels for biomolecules.
