Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 31608-22-7, C9H17BrO2. A document type is Article, introducing its new discovery.
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.
