Control of the hierarchical self-assembly of polyoxometalate-based metallomacrocycles by redox trigger and solvent composition

Madeleine Piot, Benjamin Abécassis, Dalil Brouri, Claire Troufflard, Anna Proust, Guillaume Izzet

Discrete metallomacrocycles are attractive scaffolds for the formation of complex supramolecular architectures with emergent properties. We herein describe the formation of hierarchical nanostructures using preformed metallomacrocycles by coordination-driven self-assembly of a covalent organic–…

Selective Formation of Epoxylimonene Catalyzed by Phosphonyl/Arsonyl Derivatives of Trivacant Polyoxotungstates at Low Temperature

Ourania Makrygenni, Louise Vanmairis, Sabrina Taourit, Franck Launay, Alain Shum Cheong Sing, Anna Proust, Hélène Gérard, Richard Villanneau

The catalytic performances of three organophosphonyle/arsonyle derivatives of POMs were evaluated for the epoxidation of limonene in acetonitrile, using aqueous H2O2 as the oxidant. All three W-based POMs catalysts operated without any additional transition-metal ions and displayed excellent…

On the physical properties of mixtures of nitrate salts and protic ionic liquids

Pablo Vallet, Silvia Bouzón-Capelo, Trinidad Méndez-Morales, Víctor Gómez-González, Yago Arosa, Raúl de La Fuente, Elena López-Lago, Julio Rodríguez, Luis Gallego, Juan Parajó, Josefa Salgado, Mireille Turmine, Luisa Segade, Oscar Cabeza, Luis Varela

We report a systematic study of the effect of salt concentration and its cation valence on several equilibrium and transport properties of mixtures of the model protic ionic liquid ethylammonium nitrate with monovalent (LiNO3), divalent (Mg(NO3)2 and Ca(NO3)2), and trivalent (Al(NO3)3) salts. These…

HgTe Nanocrystal Inks for Extended Short‐Wave Infrared Detection

Bertille Martinez, Julien Ramade, Clément Livache, Nicolas Goubet, Audrey Chu, Charlie Gréboval, Junling Qu, William L Watkins, Loic Becerra, Erwan Dandeu, Jean Louis Fave, Christophe Méthivier, Emmanuelle Lacaze, Emmanuel Lhuillier

Short‐wave infrared (IR) detection is currently driven by InGaAs technology which has limited the perspective of cost effectiveness and consequently slows the development of IR sensors. Since organic electronics are ineffective in this wavelength range, an alternative to conductive polymers is the…

Pseudo-automorphisms with no invariant foliation

Eric Bedford, Serge Cantat, Kyounghee Kim

We construct an example of a birational transformation of a rational threefold for which the first and second dynamical degrees coincide and are $>1$, but which does not preserve any holomorphic (singular) foliation. In particular, this provides a negative answer to a question of Guedj. On our…
