Abstract
Thermally stable dipolar and octupolar (D2d, 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.Keywords
