Cation-Driven Self-Assembly of a Gold(I)-Based Metallo-Tweezer
(Wiley, 2017-08-07)
A combination of self-complementary pi-pi-stacking interactions and metallophilic interactions triggered the self-assembly of a new digold(I) metallo-tweezer in the presence of several types of M+ ions. Titrations by ...
Surface Polarization Model for the Dynamic Hysteresis of Perovskite Solar Cells
(American Chemical Society, 2017-02)
The dynamic hysteresis of perovskite solar cells consists of the occurrence of significant deviations of the current density–voltage curve shapes depending on the specific conditions of measurement such as starting voltage, ...
Origins and mechanisms of hysteresis in organometal halide perovskites
(IOP, 2017-04)
Inorganic–organic halide organometal perovskites, such as CH3NH3PbI3 and CsPbI3, etc, have been an unprecedented rising star in the field of photovoltaics since 2009, owing to their exceptionally high power conversion ...
Hydrazine sensors development based on a glassy carbon electrode modified with a nanostructured TiO2 films by electrochemical approach
(Springer Verlag, 2017)
The authors describe a selective hydrazine sensor
that is based on the use of a film of TiO2 nanoparticles faceted
predominantly at the 101 and 001 sides. The hydrazine (Hyd)
sensor was fabricated by depositing the ...
Tripodal halogen bonding iodo-azolium receptors for anion recognition
(Royal Society of Chemistry, 2017)
The synthesis, characterization and anion binding properties of 1,3,5-tri-substituted benzene platform-based tripodal receptors containing halogen bonding (XB) iodo-imidazolium and iodo-triazolium motifs, and hydrogen ...
Imidazolium Iodide-Doped PEDOT Nanofibers as Conductive Catalysts for Highly Efficient Solid-State Dye-Sensitized Solar Cells Employing Polymer Electrolyte
(American Chemical Society, 2017)
The electrical conductivity and catalytic activity of nanofibrous poly(3,4-ethylenedioxythiophene)s (PEDOT NFs) was improved by redoping with dimethyl imidazolium iodide (DMII) as a charge transfer facilitator. Addition ...
Deleterious Effect of Negative Capacitance on the Performance of Halide Perovskite Solar Cells
(American Chemical Society, 2017)
Negative capacitance in photovoltaic devices has been observed and reported in several cases, but its origin, at low or intermediate frequencies, is under debate. Here we unambiguously demonstrate a direct correlation ...
Recent advances to understand morphology stability of organic photovoltaics
(SpringerOpen, 2017)
Organic photovoltaic devices are on the verge of commercialization with power conversion efficiencies
exceeding 10 % in laboratory cells and above 8.5 % in modules. However, one of the main limitations hindering their ...
A D3h-symmetry hexaazatriphenylene-tris-N-heterocyclic carbene ligand and its coordination to iridium and gold: preliminary catalytic studies
(Royal Society of Chemistry, 2017)
A new D3h-symmetry tris-N-heterocyclic carbene ligand has been prepared and coordinated to iridium and gold. The ligand contains an electron-poor hexaazatriphenylene core; thus, the resulting tris-NHC ligand is a poor ...
Gold Catalysts with Polyaromatic-NHC ligands. Enhancement of Activity by Addition of Pyrene
(American Chemical Society, 2017)
Three Au(I) complexes with N-heterocyclic carbene ligands
fused to polycyclic aromatic hydrocarbons (pyrene and phenanthrophenazine)
have been obtained and fully characterized. The complexes were tested
as catalysts in ...
