Synthesis and spectral properties of 4-amino-and 4-acetylamino-N- arylnaphthalimides containing electron-donating groups in the N-aryl substituent

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.

SYNTHESES AND PROPERTIES OF SOME DERIVATIVES OF N--NAPHTHALIMIDE

Syntheses of N--naphthalimide and N--naphthalimide derivatives, unreported so far in the literature have been worked out, and the products are characterized.The usefulness of some of them as optical brightening agents has been established from their fluorescence spectra.The phenomenon of an intramolecular energy transfer from the benzotriazole to naphthalimide ring systems has been observed for the derivatives of N--naphthalimide.
