Hydroxy-functionalized bipyridine and tris(bipyridine)metal chromophores: Synthesis and optical properties

A new family of symmetrically and unsymmetrically-substituted 4,4′-bis[(dialkylamino)styryl]-2,2′-bipyridine ligands, containing 1-4 hydroxy groups on their dialkylamino moieties, have been synthesized. They are readily prepared in good to excellent yields from 4,4′-dimethyl-2,2′-bipyridine and tetrahydropyranyloxy-protected [(hydroxyalkyl)amino]-benzaldehydes. These chromophores display excellent thermal stabilities, with decomposition temperatures of up to 310 °C. The influence of the OH groups on the optical properties (absorption and emission) is discussed. The synthesis of the corresponding heteroleptic and homoleptic tris(bipyridine)-metal(ii) complexes (M2+ = Ru2+, Zn2+), as building blocks for the elaboration of macromolecular NLO-phores, is also described.

Synthesis of a highly thermally stable octupolar polyimide for nonlinear optics

A new polyimide with covalently incorporated 4,4'-bis(dialkylaminostyryl)-2,2'-bipyridine chromophores is described which allows the synthesis of the corresponding NLO octupolar metallo-polymer.
