We published recently in RSC Advances a paper, reporting a new group of Lewis acidic ionic liquids that were prepared by the combination of 18-crown-6, alkali metal chloride (NaCl or KCl) and metal chloride (FeCl3, AlCl3, ZnCl2) and applied in organic reactions as catalysts.
Hydrogen halides (HCl/HBr) represent the major halogen fragments from thermal decomposition of halogen laden materials; most notably PVC and brominated flame retardants (BFRs). Co-pyrolysis of halogen-containing solid wastes with metal oxides is currently deployed as a main stream strategy to treat the halog
In a recent study published in Chemical Communications, H.F. Schaefer and coworkers showed that the Togni trifluoromethyltation reagent and some of its derivatives appear in a high-energy hypervalent form. The (kinetic) stability of these reagents is granted by the five-membered ring of their benziodoxole-ba
In this work, we study the influence of the distance between electrodes on the performance of dye-sensitized solar cells based on TiO2 using the organic dye LEG4 and a Cu(dmp)2 redox couple (dmp = di-methyl phenantroline). The solar cells are characterized by a large open circuit voltage of up to 1.03 V, and
Reversible control of the spin state of an organic molecule is significant for the development of molecular spintronic devices. Here, density functional theory calculations have been performed to study the adsorption of atomic nitrogen on a single manganese phthalocyanine (MnPc) molecule, three-layered MnPc,
We report an X-ray absorption near edge structure (XANES) study of Vanadium (V) and Nitrogen (N) dopants in anatase TiO2 thin films deposited by radio-frequency magnetron sputtering. Measurements at the Ti K and V K edges were combined with soft X-rays experiments at the Ti L2,3, O K and N K edges. Full pote
We compare the absorption and magnetic circular dichroism (MCD) spectra of a series of porphyrin oligomers – dimer, tetramer, and hexamer – bound in a linear or cyclic fashion. The MCD signal is extremely weak for low energy transitions in the linear oligomers, but it is amplified when the cyclic porphyrin h
