Abstract

A new amphiphilic compound NMOB [2-nitro-5- (N-methyl-N-decosyl) aminobenzoic acid] with both good film forming property and high optical nonlinearity was synthesized for applications of Langmuir-Blodgett films in waveguide-type second harmonic generation (SHG) devices. The near-quadratic dependence of the SHG intensity on the bilayer number, the small angle x-ray diffraction patterns and the temporal stability of alternating CdA(cadmium arachidate)/NMOB multilayers confirmed their good film structures. We obtained the hyperpolarizability (beta) of NMOB of 6.3 X 10^-50Cm³V^-2 in SI units or 1.7 X 10^-29 esu at a fundamental wavelength of 1.064 micrometers from transmitted SHG measurements which agreed with those deduced from our linear electro-optic (EO) modulated attenuated total reflection spectra at 832 nm, 633 nm and 488 nm in the order of magnitude. A resonant enhancement of the EO response near the absorption band in NMOB monolayers was observed for the first time.
