The ethynyl-linked complexes 105 were prepared and explored as potential building blocks for nonlinear optical (NLO) materials.129 Spectroscopic and cyclic voltammetry data indicate a small but real interaction between the ferrocenyl donor group and the borabenzene unit, increasing in the order RuHyper-Rayleigh scattering revealed small values for the first hyperpolarizability / , which increases in the same order.

Gold nanoparticles have large second- and third-order nonlinear susceptibilities and are therefore a promising class of nonlinear optical materials.214 We will briefly discuss several nonlinear optical processes from metal nanoparticles, such as multiphoton luminescence, hyper-Rayleigh scattering, and multiharmonic generation.

Clays and Persoons presented a new technique in 1992 for the determination of the hyperpolarizabilities of nonlinear optical compounds in solution using the hyper-Rayleigh scattering (HRS). The values for first hyperpolarizabilities can be obtained from second-order scattered light intensity. This method has several advantages over the EFISH technique it needs no electric field, and thus the experiment is simplified, the hyperpolarizability P can be directly measured, and the P values for salts can be determined as weU.

The generic experiment in hyper-Rayleigh scattering4 consists of measuring the intensity of the second harmonic l(2a>) that is scattered by a fundamental laser beam impinging on a solution of nonlinear optical chromophores in a suitable solvent. This intensity should be quadratically dependent on the fundamental intensity l(o>).
