Abstract: Electric fields represent an ideal means for controlling spins at the nanoscale and, more specifically, for manipulating protected degrees of freedom in multispin systems. Here we perform low-temperature magnetic far-IR spectroscopy on a molecular spin triangle (Fe3) and provide initial experimental evidence suggesting spin-electric transitions in polynuclear complexes. The co-presence...[more]
Absract: Iron-copper complexes have been extensively studied in the search for efficient cytochrome c oxidase models. Whereas most dinuclear materials usually focus on fine-tuning the coordination of heme-Fe, this work shows that the coordination of copper in cytochrome c oxidase models should be carefully taken into consideration. A β-cyclodextrin dimer was built around a bipyridine linker and...[more]
Abstract: The present study details the synthesis and characterization of a robust, monomeric Al–H aluminate supported by a tridentate tris-phenolate ligand, isolated as [2][Li(THF)4] and [2][N(nBu)4] salts, which were then exploited as CO2 hydroboration catalysts. As initial reactivity studies, it was observed that the nucleophilic Al–H anion in [2][C] (C = countercation [Li(THF)4]+ or...[more]
Abstract: In this study, water-soluble colloidal platinum nanoparticles (Pt NPs) have been stabilized with novel thiolated cyclodextrins (CD-SH) and their catalytic performance has been investigated. We varied the size of the CD cycle (α-CD/β-CD), the degree of thiolation (one or two thiol groups per CD), and the CD/Pt molar ratio (0.5; 0.2; 0.1; 0.05) to find the best performing water-soluble,...[more]
Abstract: A Kohn–Sham (KS) density-functional energy expression is derived for any (ground or excited) state within a given many-electron ensemble along with the stationarity condition it fulfills with respect to the ensemble density, thus giving access to both physical energy levels and individual-state densities, in principle exactly. We also provide working equations for the evaluation of the...[more]
Abstract: The discovery of a stable organic radical formed under mild, clean, and efficient light-mediated conditions is reported. The structure of the stable acridinium-based radical photoproduct was unambiguously established by single-crystal X-ray diffraction, mass spectrometry, and in solution by EPR, UV/vis, and NMR spectroscopies. The photochemical mechanism of its formation has been...[more]
Abstract: In this review, the difference between π-mers (pimers) and π-dimers (pi-dimers) will be discussed. Often interchanged or confused in the literature, these two radical interactions lead to different or even opposite physico-chemical behaviors. This review aims at clarifying the terms π-mers and π-dimers and at describing their main physico-chemical properties to address their...[more]
