Growth and characterization of an organic stilbazolium family single crystal of DESI

Organic stilbazolium family single crystal 4-N, N-diethylamino-4-N-methyl-stilbazolium Iodide (DESI) has been successfully grown from aqueous methanol solution by adopting slow solvent evaporation technique. Single crystal X-ray diffraction analysis was carried out and it shows that DESI crystal belongs to triclinic structure with P-1 space group. The presence of hydrogen in the crystal structure was determined by recording H 1 NMR spectrum. The excitation spectrum of the DESI was recorded by fluorescence analysis. The thermal study confirms the stability of the material.
