In this paper a modified two-step procedure for synthesis of N-（1-naphthyl） suecinimide （NaS） was developed, and the molecular structure of NaS was properly characterized by XRD, FT-IR, 1H NMR, DSC, etc. The results show that the melting point of our product is 159 ℃-160.5 ℃, and the characteristic infrared absorption band of carbonyl group splits into two peaks （1705cm^-3/1779cm^-3）, which are found to be quite different from the documented data （rap 147℃ -149℃; IR C=0-1700cm^-3）. Besides, photophysical spectroscopy was found to be powerful to study the molecular structure and crystal morphology of NaS compound.
