STUDIES ON THE SYNTHESIS AND CRYSTAL STRUCTURE OF N-(1-NAPHTHYL)SUCCINIMIDE

摘要

A modified two-step procedure for synthesis of N-(1-naphthyl)succinimide (NaS) was developed, and its single crystal was prepared for the first time. The molecular and crystal structures were characterized by XRD, FT-IR, ~1H NMR, DSC, etc. It has been found that the melting point (159-160.5 °C) of our product is ca 10 °C higher than the documented values, while the characteristic infrared absorption band of carbonyl group splits into two peaks (1705cm~(-1)/1779cm~(-1)) rather than one as reported in the references. These discrepancies were further examined by X-ray crystallographic analysis. Meanwhile, photophysical spectroscopy was found to be powerful to study the molecular structure and crystal morphology of organic compound.
