Preparation and optoelectronic studies of the organic compound [2-(2,3-dimethyl phenylamino)-N-Phenyl benzamide doped(PMMA)

Abstract

The optical characteristics of organic compound, 2- (2,3-dimethyl phenylamino)-N-Phenyl benzamide, for two configurations, compound solution and compound doped PMMA as a film have been investigated. The compound was characterized by elemental analysis, FTIR, 1HMR, 13CNMR and theoretical study by using AM1-semi-empirical method. The optical properties were studied by using microscopic image surface, Fourier Transform Infrared (FT-IR), Atomic Force Microscopy images and an Ultraviolet–visible spectrometer. The thermal optical nonlinearity of organic compound has been studied by using Diode laser with the wavelength 473 nm. The samples were prepared by the microwave irradiation under solvent free condition within short time and appreciable yields. The Morphological structure dependence of the optoelectronic properties was also studied. The values of optical energy gaps to the direct ( $$E_{g}^{d}$$ ) and indirect ( $$E_{g}^{in}$$ ) for the compound doped film estimated to be 2.99 eV, 2.75 eV respectively. Optically smooth and homogeneous 2-(2,3-dimethyl phenylamino)-N-Phenyl benzamide doped Poly methyl methacrylate (PMMA) film was experimentally investigated for the surface distribution by scan with 2θ. Also, the spatial self-phase modulation (SSPM) is characterized. The observed induced patterns have been simulated numerically by using Fresnel-Kirchhoff’s theory. The value of nonlinear refractive index n2 in the case of compound solution is confirmed to have less value than in a compound doped film.
