Abstract: “Two novel fluorescent naphthalimide dyes with acetylamino and amino groups were prepared for the first time by imidation, reduction and acetylation reactions from 4-nitro-1,8-naphthalic anhydride as a starting material. The synthesized dyes were characterized by FTIR, differential scanning calorimetry (DSC), 1HNMR, 13CNMR, Uv-visible and fluorometery spectroscopic techniques. The absorption spectra of the dyes were examined in DMF and wavelength maxima and molar extinction coefficients of dyes were obtained. The fluorescence properties of dyes were evaluated in DMF and their Stokes shift were determined.”
