Synthesis, growth, optical transmission and thermogravimetric studies of morpholin-4-ium 3 carboxy-2, 3-dihydropropanoate NLO single crytal

A new organic nonlinear optical (NLO) crystal, Morpholin-4-ium 3 carboxy-2, 3-dihydroxypropanoate (M4CDP) was synthesized and good optical defect free single crystals of M4CDP were grown by slow evaporation solution growth method at room temperature for the first time. UV-Vis-NIR spectrum indicates that the crystal has a very good transmittance in the entire visible and near IR regions of the spectrum suggesting the suitability of the material for NLO applications. The absorbance of M4CDP was used to calculate the refractive index n, the extinction coefficient K and both the real r and imaginary i components of the dielectric constant. The TG trace reveals that the material has good thermal stability. Thermodynamic activation parameters were computed from the TG curve using Coats and Redfern and Non linear regression methods, which confirms second order kinetics.
