Abstract
Various neutral dipolar Ir(III), Pt(II) and Ru(II) complexes characterized by a high μβ 1.907 value, as determined by the Electric Field Induced Second Harmonic generation (EFISH) technique, show a large <β HLS,1.907>, as determined by the Harmonic Light Scattering (HLS) technique. A combination of both techniques is used to evaluate the dipolar and octupolar contributions to the total quadratic hyperpolarizability, putting in evidence that the major contribution is controlled by the octupolar part.Pubblicazioni consigliate
