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.

A convenient and large scale preparation of new mono- and bis-hydroxy substituted 4,4'-bis(dialkylammostryl)-2,2'-bipyridimes is reported. Their coordination studies to [Ru(DEAS-bpy)2]2+ (DEAS-bpy = 4,4'- bis(diethylaminostyryl)-2,2'-bipyridine) are also described.
