An alternative electrolyte based on acetylacetone-pyridine-iodine for dye-sensitized solar cells

We prepared a new organic electrolyte by the reaction among acetylacetone, pyridine and iodine in 3-methoxypropionitrile. The UV-Visible spectra, conductivity measurement and ESI mass spectra were used to study this electrolyte. It was suggested that the quaternization reaction of pyridine took place in this electrolyte solution and two kinds of pyridinium iodide were formed. The efficiency of dye-sensitized solar cells (DSCs) using this electrolyte reaches 6.72%, which is higher than that of DSCs using LiI electrolyte and methylpropylimidazolium iodide electrolyte. It implies that these pyridinium iodides are effective alternative component of iodide for the electrolytes of DSCs. As this organic iodide electrolyte was in situ synthesized based on iodine instead of alkyl iodide, it will be cost-effective and facilitative for the production of DSCs. (C) 2007 Elsevier B.V.

Optical absorption spectra of lead iodide nanoclusters

Optical absorption spectra of nanoclusters of lead iodide, synthesized by the colloidal technique, have been investigated. It is shown that the absorption peaks are due to different orders of interband transitions of a nominally single size of particles rather than the first-order transitions of a number of discrete sizes of particles, as reported earlier. The model used to explain the spectra of lead iodide has also been used to account for the optical absorption peaks of colloidal mercuric iodide and bismuth tri-iodide. [S0163-1829(98)01443-X].

Oxidative Addition of Alkenyl and Alkynyl Iodides to a Au-I Complex

The first isolated examples of intermolecular oxidative addition of alkenyl and alkynyl iodides to Au-I are reported. Using a 5,5 ‘-difluoro-2,2 ‘-bipyridyl ligated complex, oxidative addition of geometrically defined alkenyl iodides occurs readily, reversibly and stereospecifically to give alkenyl-Au-III complexes. Conversely, reversible alkynyl iodide oxidative addition generates bimetallic complexes containing both Au-III and Au-I centers. Stoichiometric studies show that both new initiation modes can form the basis for the development of C-C bond forming cross-couplings.

Polycrystalline Mercuric Iodide Photodetectors for Cesium Iodide Scintillators

We have fabricated thin films of polycrystalline mercuric iodide for use as photodetectors coupled to cesium iodide scintillators. The compound semiconductor mercuric iodide has a large band gap (2.13 eV) causing a peak in its quantum efficiency (570 nm) which is well matched to the output of cesium iodide (550 nm). Single crystal mercuric iodide photodetectors coupled to cesium iodide have demonstrated a full width at half maximum (FWHM) energy resolution of 4.58% at 662 keV. Single crystals providing sufficient surface areas for coupling with scintillators; are difficult to grow and are therefore cost prohibitive to use in large field of view applications. However, polycrystalline films can be fabricated quickly and cheaply on a variety of surfaces including curved ones. We have therefore developed a thermal vapor transport method of growing polycrystalline mercuric iodide films onto transparent glass substrates coated with indium tin oxide. A palladium thin film is thermally evaporated on top of the film and the photodetectors; are operated at low voltage (up to 0.4 V/mu m) demonstrating the first use of polycrystalline mercuric iodide as a photodetector. The polycrystalline mercuric iodide films have a high resistivity producing a very low dark current typically about 1 nA per square cm at 0.4 V/mu m. When coupled to cesium iodide a FWHM energy resolution of 9% at 662 keV is obtained. The quantum efficiency at 570 nm is about 40% as compared to single crystal mercuric iodide which is 80%. We are currently optimizing the growth method to improve the quantum efficiency with the ultimate goal of obtaining an energy resolution close to that of single crystal performance.

Palladium-catalyzed reaction of aryl iodides with acetic anhydride. A carbon monoxide-free synthesis of acetophenones

[GRAPHICS] The palladium-catalyzed reaction of aryl iodides with acetic anhydride provides a straightforward and experimentally simple carbon monoxide-free route to acetophenones. The reaction tolerates a wide range of functionalized aryl iodides. Acetophenones are isolated in excellent yield with a variety of neutral, slightly electron-rich, and slightly electron-poor aryl iodides, whereas moderate yields are obtained with aryl iodides containing strongly electron-withdrawing substituents.

Design of Schiff base complexes of Co(II) for the preparation of iodide-selective polymeric membrane electrodes

The response characteristics of some iodide-selective solvent polymeric membrane electrodes based on with N,N’-bis(salicylaldehyde-n-octyl) diimine cobalt(II) (Co(II)SAODI) which is a more lipophilic substitute for a previously reported iodide-carrier are described. The electrode doped with Co(II)SAODI into a plasticized poly(vinyl chloride) membrane exhibits an anti-Hofmeister selectivity pattern with high selectivity toward iodide, long lifetime and small interference from H+. Quartz crystal microgravimetric measurements and ac impedance experiments show that the excellent selectivity for iodide is related to the unique interaction between the carriers and iodide and steric effect associated with the structure of the Schiff base ligands.

SYNTHESIS AND CHEMISTRY OF SECONDARY ALKYL IODIDE COMPLEXES OF THE FORMULA [(ETA-5-C5H5)RE(NO)(PPH3)(ICHRR’)]+BF4-

Reactions of deuterodichloromethane complex [(eta-5-C5H5)Re(NO)(PPh3) (ClCD2Cl)]+BF4- with (a) isopropyl iodide, (b) sec-butyl iodide, (c) cyclopentyl iodide, and (d) cyclohexyl iodide give secondary alkyl iodide complexes [(eta-5-C5H5)Re(NO) (PPh3)(ICHRR’)]+BF4- (3a-d) in good to high NMR yields, depending upon the quantity of alkyl iodide employed. These compounds are much less stable than analogous primary alkyl iodide complexes, but analytically pure 3d can be isolated from the reaction of (eta-5-C5H5)Re(NO)(PPh3)(CH3) and HBF4.OEt2 in neat cyclohexyl iodide (73%). Complex 3d decomposes in CD2Cl2 to give cyclohexyl fluoride, cyclohexene (74% total) and bridging halide complexes [(eta-5-C5H5)Re(NO)(PPh3)]2X+BF4- (X = I, 33%; Cl, 36%). The formation of cyclohexyl fluoride suggests BF4- participation in carbon-iodine bond cleavage. Reaction of 3d and PPh3 gives the substitution product [Ph3PC6H11]+BF4- (24%), cyclohexyl fluoride (24%), cyclohexene (30%) and (eta-5-C5H5)Re(NO)(PPh3)(I) (7, 95%). An analogous reaction of 3d and PPN+BR- gives cyclohexene (57%) and 7 (99%).

Comparative study of forward and reverse ion exchange reaction in amberlite IRA-400 by application of tracer isotope-I-131

Iodide ion exchange reaction between the resin and solution phase can be represented by RI+I-(aq)* half arrow right over half arrow right RI*+I-(aq) where RI is the resin phase having exchangeable iodide ion, I* is the radioactive I-131 tracer isotope. This exchange of radioactive iodide ions and inactive iodide ions takes place reversibly. In the present investigation, kinetics study of forward and reverse ion exchange reaction was carried out in two sets of experiments: (1) exchange between radioactive iodide ions in solution and iodide ions on ion exchanger (forward exchange), (2) exchange between radioactive iodide ions on ion exchanger and iodide ions in solution (reverse exchange). This exchange study was performed at different temperatures from 27 degrees C to 48 degrees C, for different concentrations of potassium iodide solution from 0.0025 to 0.1 M and for different amounts of ion exchange resin ranging from 0.250 g to 5.00 g. The forward and reverse ion exchange reaction rates were observed to be 0.123 min(-1) and 0.122 min(-1) under identical conditions of 1 g ion exchanger at 27 degrees C and 0.01 M iodide ion solution indicating that forward and reverse ion exchange reaction occurs simultaneously.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 88-67-5, you can contact me at any time and look forward to more communication. Recommanded Product: 2-Iodobenzoic acid.

Sorption characteristics of iodide on chalcocite and mackinawite under pH variations in alkaline conditions

In terms of long-term safety for radioactive waste disposal, the anionic iodide (1-129) with a long half-life (1.6 x 10(6) yr) is of a critical importance because this radionuclide migrates in geological media with limited interactions. Various studies have been performed to retard the iodide migration. Recently, some minerals that are likely generated from waste container corrosion, have been suggested to have a considerable chemical interaction with iodide. In this study, chalcocite and mackinawite were selected as candidate minerals for underground corrosion materials, and an iodide sorption experiment were carried out. The experiment was performed under anoxic and alkaline conditions and the pH effects on the iodide sorption were investigated in the range of pH 8 to 12. The results showed that both minerals demonstrated a noticeable sorption capacity on iodide, and the distribution coefficient (K-d) decreased as the pH increased in the experimental condition. In addition, when the alkalinity increased higher than a pH of 12, the sorption capacity of both minerals decreased dramatically, likely due to the competition of hydroxy ions with the iodide. This result confirmed that chalcocite was an especially good sorbing media for iodide under alkaline conditions with a pH value of less than 12.
