Strong Quantum Confinement and Fast Photoemission Activation in CH3NH3PbI3 Perovskite Nanocrystals Grown within Periodically Mesostructured Films
In this Communication, a synthetic route is demonstrated to obtain stabilized MAPbI3nanocrystals embedded in thin metal oxide films that display well-defined and adjustable quantum confinement effects over a wide range of 0.34 eV. Mesostructured TiO2 and SiO2 films...
Structural basis of mitochondrial dysfunction in response to cytochrome c phosphorylation at tyrosine 48
Regulation of mitochondrial activity allows cells to adapt to changing conditions and to control oxidative stress, and its dysfunction can lead to hypoxia-dependent pathologies such as ischemia and cancer. Although cytochrome c phosphorylation—in particular, at...
A Cationic Unsaturated Platinum(II) Complex that Promotes the Tautomeration of Acetylene to Vinylidene
Complex [PtMe2 (PMe2 ArDipp2)] (1), which contains a tethered terphenyl phosphine (ArDipp2 =2,6-(2,6-(i) Pr2 C6 H3)2 C6 H3), reacts with [H(Et2 O)2 ]BArF (BArF(-) =B[3,5-(CF3 )2 C6 H3 ]4(-) ) to give the solvent (S) complex [PtMe(S)(PMe2 ArDipp2)](+) (2⋅S). Although...
An Unsaturated Four-Coordinate Dimethyl Dimolybdenum Complex with a Molybdenum-Molybdenum Quadruple Bond
We describe the synthesis, molecular, and electronic structure of the complex [Mo2Me2{μ-HC(NDipp)2}2] (2), that contains a dimetallic core with a Mo-Mo quadruple bond and features uncommon four-coordinate geometry and fourteen-electron count at each molybdenum atom...
Cationic Platinum(II) sigma-SiH Complexes in Carbon Dioxide Hydrosilation
The low electron count cationic platinum complex [Pt(ItBu’)(ItBu)][BArF], 1, interacts with primary and secondary silanes to form the corresponding σ-SiH complexes. According to DFT calculations the most stable coordination mode is the uncommon η1-SiH. The reaction of...
