In this paper a modified two-step procedure for synthesis of N-(1-naphthyl) succinimide (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-1/1779cm-1), which are found to be quite different from the documented data (mp 147℃~149℃;IR C=O,~1700cm-1). Besides, photophysical spectroscopy was found to be powerful to study the molecular structure and crystal morphology of NaS compound.
