The closo-Pb-10(2-) Zintl ion in the [Ni@Pb-10](2-) cluster

2005-01-01
The cluster [Ni@Pb-10](2-), prepared from Pb-9(4-) and Ni(COD)(2), contains a new Zintl ion subunit, closo-Pb-10(2-), centered by a Ni atom.

The effect of annealing conditions on the red photoluminescence of nanocrystalline Si/SiO 2 films
Wu, Xiaochun; Bek, Alpan; Bittner, Alexander M.; Eggs, Ch.; Ossadnik, Ch.; VEPREK, S (Elsevier BV, 2003-02-03)
Nanocrystalline Si (nc-Si) embedded in a SiO2 matrix, fabricated by plasma CVD and a subsequent post-treatment shows a broad red photoluminescence (PL). In this paper, the effects of annealing temperature, atmosphere and time on the red PL from 1.75 to 1.5 eV have been investigated in detail. It is found that the spectral shift and the PL intensity from 1.75 to 1.5 eV show a strong and unique dependence on annealing conditions. For a PL approximately 1.75 eV, upon 400 °C forming gas annealing, the spectral ...
Gold(I)/Zn(II) catalyzed tandem hydroamination/annulation reaction of 4-yne-nitriles
Demir, Ayhan Sıtkı; Emrullahoglu, Mustafa; Buran, Kerem (Royal Society of Chemistry (RSC), 2010-01-01)
The tandem hydroamination-annulation reaction of 4-pentyne-nitriles in the presence of amine nucleophiles and a cooperatively operating catalyst system, consisting of Ph(3)PAuCl and Zn(ClO(4))(2), provides an efficient route to 2-aminopyrroles. Two regioisomeric 2-aminopyrroles were formed in moderate to good yields.
Characterization by Fourier transform infrared spectroscopy of hydroxyapatite co-doped with zinc and fluoride
Uysal, I.; Severcan, F.; Evis, Zafer (Elsevier BV, 2013-09-01)
Pure and Zn2+ and/or F- doped hydroxyapatite (HA) were synthesized by the precipitation method and detection of ion incorporations into the HA structure was investigated by a non invasive Fourier transform infrared (FAR) spectroscopic technique. The synthesized materials were sintered at 1100 degrees C for 1 h. The Zn2+ addition amount was kept constant at 2 mol% whereas F- amount was changed. The weight fractions of the HA and CaO were calculated by Rietveld analysis by using GSAS. Co-doping of Zn2+ and F-...
Synthesis of New Thienylene Pyrrole Monomers and Their Electropolymerizations
Eken, Serap; Carbas, Buket Bezgin; Akdağ, Akın; Önal, Ahmet Muhtar (The Electrochemical Society, 2014-01-01)
In this study, four new 2,5-dithienylpyrroles (SNS) 1-(3-fluoro-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-FPTP), 1-(3-chlorophenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-ClPTP), 1-(3-bromo-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-BrPTP) and 1-(4-bromo-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (p-BrPTP) containing meta and para substituted benzene ring at the nitrogen atom were synthesized via Paal-Knorr condensation of 1,4-di(2-thienyl)-1,4-butanedione with corresponding halo-substituted anilines. The mon...
Direct enantioselective aldol reactions catalyzed by a proline-thiourea host-guest complex
Reis, Oemer; Eymur, Serkan; Reis, Barbaros; Demir, Ayhan Sıtkı (Royal Society of Chemistry (RSC), 2009-01-01)
Proline-thiourea host-guest complex-catalyzed direct enantioselective aldol reactions have been developed, in which the catalytic activities were evaluated in the direct asymmetric aldol reactions of various aromatic aldehydes and cyclohexanone.
