Title
4-Amino-3-nitro naphthalimides—Structures and spectral properties
Abstract

4-Aryl(alkyl)amino-3-nitro-1,8-naphthalimides show substituent and solvent dependent absorbances. The substituent steric volume and character strongly influence the charge transfer within the system. Arylamino-substituted derivatives are strongly NH acidic and their spectra are highly sensitive to even a weak base such as DMF.
