4-Amino-3-nitro naphthalimides—Structures and spectral properties
摘要:
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. (C) 2012 Elsevier B.V. All rights reserved.

3,4-Diamino naphthalimides and their respective imidazoles – Synthesis, spectroscopic and theoretical investigation
particular substitution pattern starting from 3,4-diamino naphthalimides, through their respective imidazoles and quaternary N-heterocyclic carbene precursors, to corresponding carbene dimer (tetraaminoethylene). The absorption and fluorescence energies have been calculated with the PCM TDDFT formalism. PBE0 and M06 functionals were found to accurately model the distinctly different photophysical characteristics
