Naphthalene-1,4,5,8-tetracarboxylic bisimides of the general formula I 1 where the variables are defined as follows: R1 and R2 independently 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 R3 has the formula —CH2R4, —CHR4R5, or —CR4R5R6, where R4, R5, and R6 independently 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.
A naphthalene-1,4,5,8-tetracarboxylic bisimides of the general formula I
Naphthalene-1,4,5,8-tetracarboxylic bisimides of the formula I according to one or more of the preceding claims, characterized in that R1 and/or R2 independently of one another are C1-C8 alkyl, preferably tert-butyl.
Naphthalene-1,4,5,8-tetracarboxylic bisimides of the formula I according to one or more of the preceding claims, characterized in that X and/or Y are, independently of one another, halogen, C1-C20 alkylamino or C1-C20 alkoxy, it being possible for the carbon chain of C1-C20 alkoxy and of C1-C20 alkylamino to be interrupted in each case by up to four ether bridges and also to carry hydroxyl, carboxyl, amino, alkylamino, dialkylamino or sulfonic acid groups at the end, at least one of the substituents X and Y being other than halogen.
Naphthalene-1,4,5,8-tetracarboxylic bisimides of the formula I according to one or more of the preceding claims, characterized in that X and/or Y independently of one another are chlorine, bromine, C1-C8 alkylamino or C1-C8 alkoxy, at least one of these substituents necessarily being other than chlorine and bromine.
Naphthalene-1,4,5,8-tetracarboxylic bisimides of the formula I according to one or more of the preceding claims, characterized in that X and Y are other than hydrogen and halogen.
