Análisis experimental de las propiedades ópticas no lineales de los derivados del 1-aril-3-(4-metoxifenil)-5-(Benzo(d)(1,3)Dioxol-5-Yl)-2h-pirazolinas

Abstract

An experimental and theoretical study of the non-linear optical properties of two derivatives of 1-Aryl-3-(4-Methoxyphenyl)-5-(Benzo(d)(1,3)Dioxol-5-yl)-2H-pirazolines was carried out. Pyrazolines based on the excitation power of the laser, to establish its potential use in the photonics industry ¹. These compounds already synthesized and characterized by UV-vis spectroscopy, in THF as a solvent, were submitted to readings in the Z-scan system to determine different optical parameters, such as the non-linear refractive index (η2), the absorption coefficient nonlinear (β) and third order electronic susceptibility (X ⁽³⁾). For these measurements, a Cd Nd: YAG laser emitting at 532 nm, a focus of a 10 cm lens, a 1 mm iris and a cell with a length of 1 mm were used; To support the experimental results, quantum mechanical calculations were performed with the calculation level M06-2X / 6-31 G (2d). This study allowed to correlate the molecular design with the optical properties.
