Abstract: Winning combo: Porphyrins and polyoxometalates can be combined into useful architectures for energy conversion, this minireview highlights the most successful strategies developed to date. Abstract: Polyoxometalates (POMs) can act as unique reservoirs for multiple electron transfers. As POMs display only weak absorption in the visible spectrum, they can be associated with...[En savoir plus]
Abstract : In an effort to determine the thermochemistry of established organometallic transformation, the well documented reaction of alkynes with a palladacycle was investigated by isothermal titration calorimetry (ITC). Although the mechanism of the insertion of unsaturated substrates into the Pd-C bond of cyclopalladated compounds is known, so far no information is known about their...[En savoir plus]
Abstract : FID-detected nutations of the antiferromagnetic crystal form of [Y(pc)2]˙ demonstrated that its radical spin can be coherently driven in its magnetically condensed undeuterated phase and at room temperature. Liquid-helium nutations revealed additional Rabi oscillations assigned to transitions within higher-multiplicity states of finite-sized chain fragments. Graphical...[En savoir plus]
Abstract : A dimeric Cu(II) complex [Cu(II)2L2(μ2-Cl)Cl] (1) built from an asymmetric tridentate ligand (2-(((2-aminocyclohexyl)imino)methyl)-4,6-di-tert-butylphenol) and weakly coordinating anions has been synthesized and structurally characterized. In dichloromethane solution, 1 exists in a monomeric [Cu(II)LCl] (1′) (85%)–dimeric (1) (15%) equilibrium, and cyclic voltammetry (CV) and electron...[En savoir plus]
Abstract : Noncovalent interactions (NCIs) have long interested a vast community of chemists who investigated their “canonical categories” derived from descriptive crystallography, e.g., H-bonds, π–π interactions, halogen/chalcogen/tetrel bonds, cation−π and C–H−π interactions, metallophilic interactions in the broad sense, etc. Recent developments in theoretical chemistry have enabled the...[En savoir plus]
Summary: A series of porphyrin dimers have been prepared and characterized in order to form inclusion complexes with Lindqvist-type polyoxometallates. The synthesis of the porphyrin dimer has been optimized and can serve general purposes. The formation of inclusion complexes has been monitored using spectroscopic methods and moderate affinities with varying from 2.6 to 4.2 have been determined...[En savoir plus]
