    The aim of this fluorescence project was to analyse the solvatochromic properties of 1,4-DIAN sample. At the course of our work, all the products was already been proven pure by the 1H-NMR and also by the 13C-NMR spectroscopy. After the analysis, we evaluated our data of the different solvents using different mathematical models. This mathematical description of the solvatochromic behaviour of the solvents was been carried out with three mathematical models which is the Lippert-Mataga, the Kamlet-Taft and the Catalan model.Then after the structural analysis, we moved on to the fluorescence measurements with the fluorometer in order to determine the optical properties of the different solvents but then at different solutions so as to determine molar absorbance of the solution.
