Dual emission is observed from a family of simple acetylene-linked dinuclear RuII complexes, where two MLCT excited states coexist at room temperature and in fluid solution. This unique behavior is attributed to a specific substitution pattern on the bridging ligand and provides the opportunity to investigate the structural and electronic features that result in decoupling of standard nonradiative decay pathways.

Three novel Cd(II) complexes, formulated as [Cd(3,8-dibromo-1,10-phen-kappa2N,N?)(l-tar)]n (1), trans-[Cd(3,8-dibromo-1,10-phen-kappa2N,N?)2(NO3-kappa2O,O?)2]·(CH3CN) (2) and cis-[Cd(3,6-dibromo-1,10-phen-kappa2N,N?)(3-bromo-1,10-phen-kappa2N,N?)(NO3-2O,O?)(CH3OH-kappaO)](NO3) (3) (phen = phenanthroline, l-tarH2 = l-tartaric acid), have been synthesized and characterized in this paper. In coordination polymer 1, the [Cd2(3,8-dibromo-phen)2]4+ cations are bridged by l-tar ligands into an infinite 2D lamellar polymer along the c-axis, and the neighboring 2D polymers are further extended into a 3D supramolecular network by pi-pi stacking interactions. Complexes 2 and 3 are both mononuclear cadmium complexes but with different conformation (trans or cis). In the crystal packing structures of 2 and 3, molecules are arranged into three-dimensional (3D) frameworks by intermolecular hydrogen bonding and pi-pi stacking interactions.

Structural and electrochemical studies of copper(I) complexes with diethoxyphosphoryl-1,10-phenanthrolines

Two series of copper(I) complexes with diethoxyphosphoryl-substituted 1,10-phenanthroline ligands were synthesized and characterized in the solid state and in solution. The first comprised mixed-ligand CuI complexes with phenanthroline and triphenylphosphine. The second series includes bis-chelates with two phenanthroline ligands. According to the X-ray data for the six complexes, the ditopic phenanthroline ligands exhibit bidentate coordination to the copper(I) atom through two nitrogen atoms in both series. Solution equilibria involving different phenanthroline copper(I) species were studied by 1H and 31P NMR spectroscopy, electrochemistry, and spectroelectrochemistry. The solution speciation of these labile complexes is different for these two series and depends on the nature of solvent and the location of the phosphorus substituent on the phenanthroline backbone. Coordinating solvents can replace a bromide, triphenylphosphine, and even a phenanthroline ligand in the inner coordination sphere of the metal center. Copper(I) complexes with alpha-substituted phenanthrolines easily dissociate even in noncoordinating solvents such as CH2Cl2 and CHCl3. Ligand-exchange reactions leading to less sterically hindered species were observed under the utilized solution conditions. The coordination mode of the phenanthroline chelators does not change under any of the utilized solution conditions, and binding of the phosphoryl group to the metal center was never observed by spectroscopic or spectroelectrochemical methods. Copper(I) complexes with diethoxyphosphoryl-substituted 1,10-phenanthroline ligands are synthesized and characterized in the solid state and in solution by X-ray diffraction, 1H and 31P NMR spectroscopy, electrochemistry, and spectroelectrochemistry.

Novel and simple synthesis of brominated 1,10-phenanthrolines

A novel, simple, and reasonably efficient synthesis of 3,8-dibromo-1,10- phenanthroline, 3,6-dibromo-1,10-phenanthroline, 3,5,8-tribromo-1,10- phenanthroline, and 3,5,6,8-tetrabromo-1,10-phenanthroline is presented herein. The crucial role of a new catalyst (sulfur dichloride-SCl2) for the bromination of 1,10-phenanthroline is reported. The bromination of 1,10-phenanthroline monohydrate in the presence of SCl2 and pyridine yielded the brominated compounds, previously only possible through the complicated multi-step and tedious Skraup synthesis method. The application of the bromination catalyst SCl2 as a medium-strength Lewis acid is demonstrated for the first time, and the results are compared with the behaviours of known weak (sulfur chloride-S2Cl2) and strong (thionyl chloride-SOCl2) bromination catalysts. A reaction mechanism was proposed. CSIRO 2014.

Synthesis and characterization of oligothiophene-functionalized phenanthroline chromophores with symmetrical or unsymmetrical configuration

A series of promising symmetrical or unsymmetrical oligothiophene- functionalized phenanthroline chromophores was synthesized by cross-coupling reactions, and their photophysics, morphologic structure, thermal stability were characterized. All compounds which ranged from crystalline to amorphous character, provided with an excellent thermal stability. Bright blue-green emission and positive solvatochromism of these compounds were evaluated. Moreover, the redox behaviors of these compounds were performed by cyclic voltammetry. In a word, the chemical and physical properties of these compounds could be efficiently regulated by the symmetrical or unsymmetrical molecular configuration.
