Studies on Third Order Nonlinear Optical Property and Biological Activity of DL-Methioninium Maleate for the Applications in Optoelectronics and Biomedical Field

DL-methioninium maleate [DLMM] compound is one of the amino acid compounds exhibiting antibacterial activity besides nonlinear optical behavior.The compound was grown by using slow evaporation technique based on the knowledge of the classical theory of nucleation kinetics.The lattice parameters of the grown crystal were determined as a = 11.06Å, b = 5.67 Å, c = 19.70Å, α = 90 • , β = 102.59• and γ = 90 • with the volume of unit cell as 1229 Å 3 by single crystal X-ray diffractometer.The functional groups present in the grown material were confirmed by FTIR study.The molecular structure of the grown compound was analyzed by 1 H NMR and 13 C NMR spectral studies.The third order nonlinear optical parameters of the material were calculated as n2 = 3.32 cm 2 /W, β = 3.20 cm/W, and χ (3) = 1.02 esu by using Z-scan technique.Finally, Agar disc diffusion method was employed to discuss the biological activity of the grown compound.The grown DLMM compound is therefore an useful material to find applications in optoelectronics and biomedical field due to its third order nonlinear behavior and biological activity.
