Organo lead mixed -ha l ide perovsk i t e s such as CH3NH3PbX3−aX′a (X, X′ = I, Br, Cl) are interesting semiconductors because of their low cost, high photovoltaic power conversion efficiencies, enhanced moisture stability, and band gap tunability. Using a combination of optical absorption spectroscopy, powder X-ray diffraction (XRD), and, for the first time, Pb solid state nuclear magnetic res...

In the last century the production and application of halides assumed an ever greater importance. In the fields of medicine, dentistry, plastics, pesticides, food, photography etc many new halogen containing compounds have come into everyday use. In an analogous manner many techniques for the detection and determination of halogen compounds and ions have been developed with scientific journals ...

in this article, theoretical studies on the selective complexation of the halide ions (f¯, cl¯ and br¯) and ion pairs (na+f¯, na+cl¯ and na+br¯) with the cyclic nano-hexapeptide (cp) composed of l-proline have been performed in the gas phase. in order to calculate the dispersion interaction energies of the cp and ions, dft-d3 calculations at the m05-2x-d3/6-31g(d) level was employed. based on t...

The photochemical stability of encapsulated films of mixed halide perovskites with a range of MAPb(I1-x Brx )3 (MA=methylammonium) compositions (solid solutions) was investigated under accelerated stressing using concentrated sunlight. The relevance of accelerated testing to standard operational conditions of solar cells was confirmed by comparison to degradation experiments under outdoor sunli...

In the performance of routine determinations of serum chloride by the automated method, which depends on halide displacement of mercury from the thiocyanate to allow formation of ferric thiocyanate complex, 4 cases of bromide poisoning were detected. Experimental evidence shows the halide substitution to be an equilibrium, with higher formation constants for the heavier halide ions. As a result...

Lead-free organic-inorganic tin halide perovskites were prepared and investigated by a rapid screening technique utilizing a modified scanning electrochemical microscope (SECM). We studied liquid junction photoelectrochemical (PEC) solar cells based on p-type methylammonium tin halide (MASnI3-xBrx) perovskites employing the benzoquinone (BQ) redox couple, BQ/BQ , in dichloromethane (CH2Cl2). We...

The magnetic propertie~ of a series of ternary tetrathiafulvalenium (TTF + ) salts incorporating, wiIhin a unique antiperovskite structure, a discrete halide (Y Cl-, Bror I-j in addition to an octahedral molybdenum halide cluster dianion Mo6X(I (with X = Cl or Br), are described, The preparation and structural chemistry of the materials of general formula

Novel organocobalt complexes featuring weak C-CoL2 bonds (L = acetylacetonate) are prepared and used as sources of halomethyl radicals. They permit the precision synthesis of α-halide functionalized and telechelic polymers in organic media or in water. Substitution of halide by azide allows derivatization of polymers using the CuAAC click reaction.

A self-assembled poly(amide-triazole) physical gel (1) was found to show responsive behaviour towards halide anions, while the corresponding monomeric (2) and dimeric homologues (3) were non-gelating. In the presence of halide anions, polymer gel 1 collapsed to become a solution, but could be restored back to the gel state after addition of a AgNO3 salt.
