4-Alkylamino-N-alkylnaphthalic-1,8-imides and 2-alkylamino isomers have been synthesised by the reaction of 4-nitro- and 2-nitronaphthalic anhydrides respectively with primary amines in aprotic solvents in which reaction the nitro group in 3-nitronaphthalic anhydride is unreactive. Unsymmetrical compounds in the 2- and 4-series are derived from either the appropriate 4-nitro-N-alkylnaphthalic-1,8-imide or for 4-dilakylamino compounds from 4-nitronaphthalic anhydride by reaction with a secondary amine and then the 4-dialkylaminonaphthalic anhydride with a primary amine.

A number of substituted 1,8-naphthalimides and naphthalic anhydrides have been prepared and their absorption and fluorescence properties in absolute ethanol have been determined.In the absence of an alkylamino substituent in the naphthalene ring, the compounds are colourless and weakly fluorescent.In the presence of such a substituent they become yellow and frequently fluoresce strongly with quantum yields of the order of 0.8.
