Xin, Xia; Pietraszkiewicz, Marek; Pietraszkiewicz, Oksana; Chernyayeva, Olga; Kalwarczyk, Tomasz; Gorecka, Ewa; Pociecha, Damian; Li, Hongguang; Holyst, Robert published an article in 2012, the title of the article was Eu(III)-coupled luminescent multi-walled carbon nanotubes in surfactant solutions.Synthetic Route of 75449-26-2 And the article contains the following content:

A carbon nanotube/inorganic hybrid material was fabricated by coupling Eu(III) complexes onto multi-walled carbon nanotubes (MWCNTs). Successful coupling was verified by XPS measurement where a clear signal from Eu3d was identified. When sonicated in hexaethylene glycol monododecyl ether (C12E6) or sodium dodecyl sulfate (SDS) aqueous solutions, the MWCNTs with Eu-complex attached (denoted as Eu-MWCNTs hereafter) can be dispersed. UV-visible measurements on a dilute dispersion of Eu-MWCNTs in SDS aqueous solution reveal the characteristic absorption from Eu(III) complexes, which gives further proof of the successful coupling. The strong luminescent properties of Eu-MWCNTs allow them to be observed directly under a fluorescence microscope. Eu-MWCNTs can undergo continuous movements in C12E6 or SDS dilute solutions When Eu-MWCNTs are incorporated into the lyotropic liquid crystal phase formed by C12E6 (above 40% by weight), however, movements were hindered. Small angle x-ray scattering measurements showed that Eu-MWCNTs are ordered in the lyotropic liquid crystal. Fluorescence microscopy observations reveal that the luminescent properties of the Eu-MWCNTs were not affected by the liquid crystalline surfactant matrix. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Synthetic Route of 75449-26-2

Hurley, Nicholas J.; Rawson, Jeremy M.; Pilkington, Melanie published an article in 2015, the title of the article was 3,3′-Di(pyrazinamoyl)-2,2′-bipyridine: rational ligand design for the self-assembly of a 1-D coordination polymer.Recommanded Product: 75449-26-2 And the article contains the following content:

A new ligand, 3,3′-di(pyrazinamoyl)-2,2′-bipyridine, L3H2 was prepared and is comprised of distinct binding domains capable of facilitating the formation of coordination polymers. Reaction of L3H2 with [Cu2(OAc)4(H2O)2] in the presence of Et3N·HCl affords {[Cu3(L3)(Cl)(OAc)3]·H2O·MeOH}n (1) in which the [L3]2- anion binds two unique copper ions in a bis-tridentate fashion via amide and pyridyl N atoms. This bimetallic unit is linked to an equivalent unit via a pair of 1,3-acetato and μ-chloro bridges to afford a tetrameric [Cu4(L3)2Cl2(OAc)2] core. Coordination of one of the pyrazole substituents from each ligand to a third copper center of a rigid paddlewheel [Cu2(OAc)4] unit leads to a unique 1-dimensional polymeric structure. Magnetic studies of 1 reveal that the magnetism can be described in terms of two sets of exchange interactions; strong antiferromagnetic interactions between the two copper centers within the paddle-wheel (J/k = -190 K) and a combination of weaker ferro- and antiferro-magnetic interactions within the tetrameric core (J’/k = -5.7 K and J”/k = +2.1 K). The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Recommanded Product: 75449-26-2

On August 31, 2002, Rice, Craig R.; Onions, Stuart; Vidal, Natalia; Wallis, John D.; Senna, Maria-Cristina; Pilkington, Melanie; Stoeckli-Evans, Helen published an article.Recommanded Product: [2,2′-Bipyridine]-3,3′-diamine The title of the article was The coordination chemistry of 3,3′-diamino-2,2′-bipyridine and its dication: Exploring the role of the amino groups by X-ray crystallography. And the article contained the following:

The synthesis and structural chem. of new divalent transition metal complexes of the bis-bidentate ligand 3,3′-diamino-2,2′-bipyridine (L1) and its dication L1H2 are described. Ligand L1 reacts with salts of divalent transition metals (Cu(II), Mn(II) and Zn) to afford the (1:1) metal-ligand complexes (2a-2d) as well as the tris complexes (3a-3f). All complexes were fully characterized by spectroscopic methods and the following compounds [Cu(L1)Cl2]2 (2a), [Cu(L1)(OAc)2] (2b), [Zn(L1)3][OTf]2 (3a), and [Zn(L1)3][ZnCl4] (3e and 3f) were structurally characterized. Results from single crystal x-ray diffraction measurements indicate that formation of an intramol. H bond between the two amino groups allows the ligand to coordinate divalent metal ions through their diimine binding sites. Also, the structure of compound 2a reveals that it crystallizes as a dimer in which each Cu ion is bound to two pyridine N atoms and two chloride ions in a distorted square planar arrangement, with a long axial contact from a neighboring amino group completing the approx. square-pyramidal geometry at CuII. Complexation of this ligand in acidic conditions afforded [Cu(L1H2)Cl4] (4), as well as the two salts [L1H2][CuCl4] (5a) and [L1H2][ZnCl4] (5b). All three compounds were structurally characterized and the dication (L1H2) displays a different coordination preference for the chelation of metal ions. In all three cases, both of the heterocyclic N atoms of the ligand are protonated, thus preventing chelation to the metal ion, although for compound 4 crystallog. studies reveal that the two amino functionalities coordinate the Cu(II) ion.
