AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Using density functional theory with a van der Waals-corrected functional, we elucidate how CO 2 binds to a novel "BTT-type" metal-organic framework (MOF) featuring open metal centers. We show that CO 2 binds most favorably to open metal cation sites, but ...
This thesis is concerned with supramolecular architectures assembled at metal surfaces. The investigations pursued two objectives. On the one hand, the focus was placed on the fabrication of low-dimensional surface-supported network structures by applying ...
The high chemical reactivity of unsaturated metal sites is a key factor for the development of novel devices with applications in sensor engineering and catalysis. It is also central in the research for sustainable energy concepts, e.g., the efficient prod ...
Hexanuclear coordination cages of the formula [(C5Me4R)M(C7H3NO 4)]6 (M = Rh, Ir; R = Me, H) were obtained by stepwise reaction of [(C5Me4R)M(μ-Cl)Cl]2 with, first AgOAc and then pyridine-3,5-dicarboxylic acid. Crystallographic analyses show that the cages ...
Homo- and heterobimetallic complexes of the late transitions metals have been synthesized by metathesis reactions of the corresponding chloro-bridged dimers. These reactions have the advantage of being fast and giving rise to structurally defined products ...
The first part of this work deals with oxidative addition reactions of the triangulo platinum cluster [Pt3(μ-CO)3(PCy3)3]. Reactions with the electrophilic molecules ICH2CN and X2 (X = I and Br) and with the weakly polar reagent Ph3SnH have been studied. A ...
N-Substituted (3S,4S)- and (3R,4R)-pyrrolidine-3,4-diols 9 and 10, respectively, were derived from (+)-L- and (-)-D-tartaric acid, respectively. Compounds 9k, 91, and 9m with the N-substituents, BnNH(CH2)(2), 4-Phc(6)H(4)CH(2)NH(CH2)(2) and 4-ClC6H4CH2NH(C ...
Enantioselective synthesis of a 3-D inorganic net has been achieved leading to metal–organic frameworks built from cobalt-oxide helices in which handedness is controlled by the chirality of the linked ligand. ...
A tetragonal molybdenum nitride (β-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N2 + H2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; PH2=11bar) of a series of para-substitut ...
A tetragonal molybdenum nitride (beta-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N-2 + H-2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; P-H2 = 11 bar) of a series of para- ...
