Abstract
A new organic and nonlinear optical material namely (4-chlorophenyl) (4-hydroxypiperidin-1-yl) methanone [HPCP] was synthesized from the mixture of 4-hydroxypiperidiene, triethylamine, and 4-chlorobenzoyl chloride by solution growth technique. The 3D structure of the title crystal has been derived using the X-ray diffraction (XRD) spectrum. The compound was crystallized in the orthorhombic crystal system with non-centrosymmetric space group Pca21. Optical properties of the as-grown compound have been elucidated through 1H-NMR, UV-Visible, FTIR, and PL spectral studies. The melting point, stages of mass decay, and thermal stability of the synthesized material were obtained by TG/DTA thermal analysis. Vickers microhardness test was performed to comprehend its mechanical strength. The second harmonic generation (SHG) efficiency was estimated by employing Q-switched high energy, Nd: YAG the laser source, and the SHG efficiency was found to be 1.73 times that of KDP, the reference crystal.
