“…The ligands OX (4,4′-bis(5-phenyl-1,3,4-oxadiazole)-2,2′-bipyridine) and DPA (4,4′-bis(2-(4-diphenylaminophenyl))-2,2′-bipyridine) were prepared by literature methods. 13,15,22 All metal complexes were synthesized by established literature techniques with minor variations. 12,23 The precursor [Cu(PPh 3 ) 4 ]BF 4 was synthesized by the method of Rader et al 24 [Re(CO) 3 Cl(OX)].…”

“…To this end, electron-withdrawing and -donating groups such as oxadiazoles and diphenylanilines are often appended to metal complexes to induce electron- and hole-transporting properties, respectively. Oxadiazole-substituted complexes ,, and complex polymers have been investigated for their use in electroluminescent and sensitizing applications. A number of groups have substituted ruthenium-based solar cell dyes with diphenylanilines, attached via ethenyl linkers, in order to improve the solar absorption profiles. − In every case this induced strong absorption bands at ca.…”

Transition-metal complexes of the types [Re(CO)3Cl(NN)], [Re(CO)3py(NN)]+, and [Cu(PPh3)2(NN)]+, where NN = 4,4′-bis(5-phenyl-1,3,4-oxadiazol-2-yl)-2,2′-bipyridine (OX) and 4, 4′-bis(N,N-diphenyl-4-[ethen-1-yl]-aniline)-2,2′-bipyridine (DPA), have been synthesized and characterized. Crystal structures for [Re(CO)3Cl(DPA)] and [Cu(PPh3)2(OX)]BF4 are presented. The crystal structure of the rhenium complex shows a trans arrangement of the ethylene groups, in agreement with density functional theory calculations. The structure of the copper complex displays the planar aromatic nature of the bpy-oxadiazole ligand. Density functional theory modeling of the complexes was supported by comparison of calculated and experimental normalized Raman spectra; the mean absolute deviations of the complexes were <10 >cm-1. The Franck-Condon state was investigated using UV-vis and resonance Raman spectroscopic as well as density functional theory computational techniques. It was shown that the lowest energy absorption peaks are metal to ligand charge transfer and ligand-centered charge transfer for the oxadiazole-and diphenylaniline-substituted bipyridine ligands, respectively. The lowest energy excited states were characterized using transient emission and absorption spectroscopic techniques in conjunction with density functional theory calculations. These showed that the DPA complexes had ligand-centered nonemissive "dark" states with lifetimes ranging from 300 to 2000 ns.

“…One method to balance the injection/transport rates of hole and electron is incorporate the hole-transporting group and electron transporting group into one molecule as the emitting layer (Gong et al, 1998;Kim et al, 2001;He et al, 2006;Tamoto et al, 1997). In this work, a new ligand, which contains both hole transporting triphenylamine and electrontransporting 1,3,4-oxadiazol moieties, has been synthesized and its structure studied in detail.…”

A novel bismuth(III) complex with 2-amino-3-carbomethoxy-4,5,6,7-tetrahydrobenzo[b]thiophene (ACTT) as a ligand have been synthesized. The novel complex was characterized on the basis of its IR, NMR, elemental analysis and MS spectral data. It was found that the ligand behaves as a monodentate chelating agent and bonds to the metal ion through the nitrogen atom of the amino group to form the [Bi III (ACTT) 6 ]Cl 3 complex. The new complex compound displayed significant antimicrobial activity (MIC = 8-32 μg/mL) against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Shigella flexneri, Candida albicans, Candida tropicalis and Cryptococcus neoformans.
