摘要: 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 beta0 values point out the superiority of octupoles versus dipoles in terms nonlinearity/transparency tradeoff. octahedral tris(bipyridyl)zinc(II) complex exhibits a very large value (241 x 10-30 esu), which is largest ever reported for molecules.
