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 synthesis of push-pull polyenes designed for the elaboration of efficient nonlinear optical materials

, p. 6923 - 6926 (2007/10/03)
We present a convenient and versatile synthetic approach towards push-pull phenylpolyenes and diphenylpolyenes bearing a hydroxyl functional group. These chromophores are of particular interest for the design of efficient nonlinear optics materials due to their large optical nonlinearities, their transparency in the near IR and their capacity to be incorporated into polymeric materials.
Synthesis and coordination studies of new mono- and di-hydroxy functionalized 4,4'-dialkenyl-2,2'-bipyridines

, p. 6869 - 6872 (2007/10/03)
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.
