Synthesis and Physicochemical Investigation of THz Material: 4–Ethoxy Benzaldehyde–4’–N’–Methyl Stilbazolium Hexafluorophosphate (EMBSHP)

Single crystals of organic optic material 4–Ethoxy Benzaldehyde–4'–N'–Methyl Stilbazolium Hexafluorophosphate (EMBSHP) were grown by slow evaporation technique at room temperature using acetone – water (3:1) mixed solvent. The grown crystal was subjected to single crystal X – ray diffraction analysis to identify the crystal structure and lattice parameter. The crystal belongs to the triclinic crystal system. The composition of the crystal was studied by CHN analysis. The presence of functional groups of the title crystal were confirmed from the FTIR spectral studies. The optical transmission range of the grown crystal was measured by UV – Vis – NIR spectral studies. The melting point of the grown crystal was found from DSC analysis.
