Paper Abstract

Hyper-Rayleigh scattering is used to investigate the nonlinear optical properties of novel organometallic compounds. For a series of ruthenium and gold y-arylacetylides, including some bimetallic complexes, the influence of the organometallic donor group, chain length and type of acceptor on the quadratic hyperpolarizability is studied. The hyperpolañzabiities found are among the highest (1027 esu) known for organometallic compounds. Moreover, electric-field induced second-harmonic generation confirms these values and indicates that only one major tensor component is present. Keywords: hyper-Rayleigh scattering, nonlinear optics, second-harmonic generation, organometallic compounds
