ABSTRACTIn this paper some of the more important Hyper Rayleigh Scattering (HRS) Measurements performed in our laboratory are reviewed. The results of experiments conducted on polymers, the protein Bacteriorhodopsin, retinal derivatives and octopoles are presented. Basic HRS theory, along with a brief description of the HRS set-up, is also included.We demonstrate that the experimental simplicity of HRS allows for an accurate determination of the first hyperpolarizability of molecules that could not have been measured by the more traditional Electric Field Induced Second Harmonic Generation (EFISHG) technique.

ABSTRACTNonlinear optical dendritic macromolecules, called “azobenzene dendrons”, having a branching structure modified with a second-order nonlinear optical chromophore has been synthesized. An electron donor and acceptor azobenzene chromophore having a large molecular hyperpolarizability of β0=150E-30 esu, was chosen. The electronic structure of synthesized dendrons, which were expected to become dipolar due to their intermolecular attractive interaction, was proven by second-order nonlienar optical properties. The molecular hyperpolarizabilities of azobenzene dendrons were measured by the hypr-Rayleigh scattering technique. The highest molecular hyperpoalrizability was found to be 3,010E-30 esu for an azobenzene dendron having 15 chromophoric unit, where each chromophore coherently contribute to the second harmonic generation. This level of the molecular hyperpolarizability was much larger than that for a monomeric azobenzene chromophore.

Orientational Distribution Function

Since the introduction of Hyper-Rayleigh scattering (HRS) as a measurement technique for the first hyperpolarizability of molecules in solution,1 the importance of fluctuations was realized.2 For isotropic solutions, a combination of the spatial and temporal orientational fluctuations causes the instantaneous and local deviation from macroscopic centrosymmetry, necessary to observe a second-order signal. The fluctuations in the spatial orientational distribution function of nonlinear optical chromophores cause an HRS signal that fluctuates as a function of position in solid samples. The correlation length, characterizing the decay of the autocorrelation function of this fluctuating signal, indicates the degree of spatial correlation between these chromophores. The development of femtosecond HRS was instrumental for the study of orientational correlations.3

In this work, the density functional theory (DFT) calculation combined with a polarizable continuum model (PCM) was used to study the solvent media effects on the electrical and geometrical behaviors of the Schiff-base derivative, (E)-4-[({4-[(pyridin-2-ilmetilideno)amino]phenyl}amino)-metil]fenol (EPAF). The linear and nonlinear optics parameters, as the dipole moment, linear polarizability, and first and second hyperpolarizabilities, were calculated at DFT/B3LYP/6-311+G(d) level, for the EPAF molecule in several solvent media. The dynamic behavior of the Hyper-Rayleigh Scattering (HRS) first hyperpolarizability was studied as function of the electric field frequency. The results presented for HRS first hyperpolarizability suggest that the studied crystal has good nonlinear optical properties. In addition, the gap energy was calculated from the HOMO-LUMO energies difference in several solvent media. The EPAF crystal intermolecular interactions were studied by the Hirshfeld surface analysis. The third-order electric susceptibility χ(3) of the crystal EPAF was also calculated, indicating the EPAF crystal as a promising candidate for NLO applications in photonic and optoelectronic devices.

The Way

New acidochromic and photochromic compounds with nonlinear optical properties have been designed and synthesized. The hyperpolarizabilities of the zwitterionic colored forms have been quantified with polarized hyper-Rayleigh scattering experiments. The static value of oxazolidino-indoline 2 is found to be as high as Disperse Red One. This opens the way to novel multi-addressable NLO-systems.
