Novel Organometallic Compounds for Nonlinear Optics

Hyper-Rayleigh scattering is used to investigate the nonlinear optical properties of novel metal (ruthenium, nickel and gold) σ-arylacetylide complexes. The influence of the organometallic donor group and conjugating bridge on the quadratic hyperpolarizability is studied. For all organic ligands, the addition of the metal (donor) group is shown to increase the static hyperpolarizability by a factor of 2, 4 and 7 for gold, nickel and ruthenium complexes, respectively. Moreover, replacement of phenyl with a heterocyclic ring is demonstrated to enlarge the hyperpolarizability in the case of gold and ruthenium compounds.

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.

Linear And Nonlinear

New push-pull second harmonic generation (SHG) chromophores 2 were synthesized in order to study their linear and nonlinear optical properties. The donor-acceptor π-conjugated systems 2 were prepared in good to excellent yields by a simple aldol-type condensation of the precursor aldehydes 1 with 6-nitro-2-methyl-1,3-benzothiazole in the presence of NaOH. Hyper-Rayleigh scattering in dioxane solutions was used to evaluate their second-order nonlinear optical properties. The experimental results showed that the optical (linear and nonlinear) properties are influenced by the electron-donor strength of the groups of the π-conjugated bridge. The vinyl-benzothiazole derivative 2b, with methoxyl as the donor group, exhibited the largest first hyperpolarizability β (1660 × 10−30 esu, 40 times greater than the standard reference pNA molecule) and the highest decomposition temperature (Td = 360 °C). The good balance between nonlinearity and thermal stability makes this compound a promising candidate as second harmonic generator (SHG) for nonlinear optics.
