experimental part, p. 1233 - 1240 (2010/10/04)
A method for the synthesis of N-aryl-substituted 4-amino-and 4-acetylaminonaphthalimide derivatives with mono-and dialkoxy groups or a 15-crown-5 moiety in the N-aryl substituent is described. The introduction of electron-donating alkoxy groups into the benzene ring of the N-aryl fragment results in fluorescence quenching of the naphthalimide chromophore, which is most pronounced in the spectra of N-acetyl derivatives. The photophysical properties of the synthesized 4-amino-and 4-acetylaminonaphthalimides depend on the solvent polarity and its specific solvating ability due to H-bonding. The crown-containing compounds are promising fluorescent chemosensors for metal cations. ; 2009 Springer Science+Business Media, Inc.

The nitro group in the isomeric condensation products of 4-nitronaphthalic-1,8-anhydride with 1,2-diaminobenzene namely 3-nitro and 4-nitro-7H-benzimidazo[2,1-a]benz[de]isoquinolin-7-one is displaced by reaction with 1-octylamine, to give in the case of the 4-nitro compound the highly fluorescent 4-octylamino derivative. The condensation product from 4,5-dinitronaphthalic-1,8-anhydride and 1,2-diaminobenzene afforded, by nitro group displacement with either 1-butylamine or 1-octylamine, complex mixtures without exhibiting significant fluorescence.
