STRUCTURAL, OPTICAL AND MECHANICAL PROPERTIES OF ORGANIC SINGLE CRYSTAL: 4-N, N-DIETHYLAMINO-4- N-METHYL-STILBAZOLIUM IODIDE (DESI)

Abstract

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. Its absorption spectrum was found by UV-Vis spectrum. Hardness study was also carried out for applying different loads.
