The optical nonlinear properties of a new synthesized azo-nitrone compound

摘要

In this article the preparation of compound heterogeneous azo-nitrone is introduced. Novel compound resulted via the reaction between azoaldehyde and N-phenylhydroxylamine through several steps. (Z)-1-(2-hydroxy-3-methoxy-5-((E)-(3-nitrophenyl) diazenyl) phenyl)-N-phenylmethanimine oxide derived from N-phenylhydroxylamine with (E)-2-hydroxy-3-methoxy-5-((3-nitrophenyl) diazenyl) benzaldehyde. The novel azo-nitrone compound has been identified via infrared spectroscopy (FT-IR), NMR proton spectrum (H-1 NMR) and mass spectrometry (Mass spectra) as well as measurement of its melting point. The nonlinear index of refraction of the prepared compound is determined separately via the patterns of diffraction ring and the Z-scan. Ring patterns are simulated using the Fresnel-Kirchhoff diffraction theory. The optical limiting property of the prepared compound is tested where it is proved that such compound might be used as an optical limiter.
