PCCP [POMAM]

Abstract Molecular triangles with competing Heisenberg interactions and significant Dzyaloshinskii–Moriya interactions (DMI) exhibit high environmental sensitivity, making them potential candidates for active elements for quantum sensing. Additionally, these triangles exhibit magnetoelectric coupling, allowing their properties to be controlled using electric fields. However, the manipulation and...[En savoir plus]

PCCP / COVER [LCQ]

Abstract The design of enantiomerically pure circularly polarized luminescent (CPL) emitters would enormously benefit from the accurate and in-depth interpretation of the chiroptical properties by means of jointly (chiroptical) photophysical measurements and state-of-the-art theoretical investigation. Herein, computed and experimental (chiro-)optical properties of a series of eight enantiopure...[En savoir plus]

Batteries and Supercaps [POMAM]

Graphical Abstract: A metal-free porphyrin (TDPP) with a diphenylamino-Phenyl group is proposed as an electrode for aluminum-based batteries. The electrochemical performance is explored thoroughly. The extended porphyrin conjugated structure by the diphenylamino-phenyl groups shows a reversible capacity of 83 mAh g−1 at 1 A g−1 after 200 cycles and good cycling stability.   Reference...[En savoir plus]

Org. Biomol. Chem. [SOPhy]

Abstract We developed a chemoselective metal-free access for the 1,2- and 2,3-semireduction of CF3-N-allenamides. The enamide functionality of CF3-substituted N-allenamides could be efficiently reduced by Et3SiH/BF3·OEt2 in total regioselectivity and good stereoselectivity, whereas DBU promoted the isomerization of the resulting allyl amide leading exclusively to the E-configurated...[En savoir plus]

Chemistry—A European Journal [ECMC]

Graphical Abstract Two for the price of one! Depending on the experimental conditions, two dramatically different diphosphanes can be obtained from diphenyl(2-phosphanylphenyl)phosphane and an α-cyclodextrin-derived dimesylate. The metal confining properties of the cavity-shaped ligands have been exploited to produce luminescent chelate [CuX(PP)] complexes (X=Cl, Br,...[En savoir plus]

Journal of Catalysis [POMAM]

Abstract The direct CO2 conversion to liquid fuels by catalytic hydrogenation (CO2-based Fischer-Tropsch synthesis, FTS), is a sustainable approach to reduce CO2 emissions. This challenging reaction proceeds through tandem catalysis involving reverse water gas shift reaction to produce CO and subsequent traditional CO-FTS. Unmodified Co-based catalysts allow performing the reaction at low...[En savoir plus]

Chemistry - A European Journal [LCSOM / LASYROC]

Abstract Telluronium salts [Ar2MeTe]X were synthesized and their Lewis acidic properties towards a number of Lewis bases were addressed in solution by physical and theoretical means. The structural X-ray diffraction analysis of 21 different salts revealed the electrophilicity of the Te centers in their interactions with anions. Telluroniums’ propensity to form Lewis pairs was investigated with...[En savoir plus]
