Abstract

The title compound

3-(3

5-dichlorobenzylideneamino)benzoic acid was obtained by the condensation of 3-aminobenzoic acid and 3

5-dichlorosalicylaldehyde

and the structure of it was determined by

H NMR

and high-resolution mass spectra. We have studied its fluorescence performance and thermal stability. The UV and fluorescence spectrums reveal that the title compound possesses favorable properties of photochromism and thermochromism in DMF solution. The analysis also shows that there is a linear relationship between its absorbance and time or temperature

which further demonstrate its photo-and thermochromic properties.
