Synthesis, characterization, and third-order nonlinear optical properties of a new neolignane analogue†
Abstract
Recently, a wide number of pharmacological activities, such as anti-leishmanial, antioxidant and antitumor, have been discovered for neolignane analogues. To provide a view of the non-linear optical behavior of the third order of the crystal 2-(4-nitrophenoxy)-1-phenylethanone (NPH-PE) in the static and dynamic cases, we calculated its linear polarizability (α) and second hyperpolarizability (γ). We used a new supermolecule approach combined with an iterative electrostatic system whose atoms of the neighboring molecules are represented by point charges. A comprehensive investigation of NPH-PE is reported by single crystal X-ray diffraction and FT-Raman and NMR spectroscopy. In addition, a combination of density functional theory (DFT) with the CAM-B3LYP functional and the 6-311+G(d) basis set was used to calculate the molecular structure optimization, the vibrational frequencies, and the intensity of the vibrational bands. Concerning the values of the third-order optical nonlinearity, the second hyperpolarizability of the embedded molecule showed an increase of 125 058% in comparison with the corresponding result in the static case.
