ResumoThe synthesis of 4,4′-bis(dialkylaminostyryl)-6,6′-dimethyl-2,2′-bipyridine ligands is described; the corresponding tetrahedral bis(bipyridyl) copper(I) complexes have been prepared, and their second-order nonlinear optical properties determined by harmonic light scattering (HLS) at 1.34 µm; these new octupolar complexes exhibit large molecular hyperpolarisabilities β.
