| Abstract: | N-（4-Hydroxyphenyl） maleimide（HPM） was prepared and its structure was characterized by IR and NMR. The ultraviolet spectra of HPM solutions in three different solvents （methanol, tetrahydrofuran, dichloromethane）were studied. It was found that the absorption peak in 210-250 nm was sensitive to the polarity of the solvent, however the other absorption peak at 275 nm remained basically stable when the concentration or the polarity of the solvent was changed. The absorption at 275 nm is reasonably considered as a characteristic peak of HPM in the ultraviolet quantitative analysis. The other absorption peak in 210-250 nm which is sensitive to the solvent and concentration can be taken to study the interactions between HPM and other molecules. |
