Zinc(II) as a versatile template for the design of dipolar and octupolar NLO-phores

Article abstract of DOI:10.1021/ja025705a

Thermally stable dipolar and octupolar (D_2d, D₃) NLO-phores are readily accessible by combining one, two, or three 4,4′-bis(dialkylaminostyryl)-[2,2′]-bipyridyl ligands with zinc(II) salts. The off-resonant β₀ values point out the superiority of octupoles versus dipoles in terms of nonlinearity/transparency tradeoff. The octahedral tris(bipyridyl)zinc(II) complex exhibits a very large β₀ value (241 × 10^-30 esu), which is the largest ever reported for octupolar molecules. Copyright
