| In this thesis, hydroxy aldehyde substituted aniline Schiff Base compounds 1 5 were synthesized in anhydrous ethanol reflux with substituted aniline and p-hydroxybenzaldehyde as raw material. 1H NMR, 13C NMR, IR, melting point, and other means were applied to characterize the structure of the five molecules, the results of which were maximum absorption wavelength of 314 331 nm in UV spectrum, emission spectrum wavelength of 374 390 nm with strong fluorescence in fluorometric assay. |
