Cell [IFM]

Tweet: The IFM team provides the first structural interpretation of the allosteric modulation at the α7 nicotinic acetylcholine receptor in collaboration with world-renowned structural biologists and electro physiologists from the University of California San Diego (USA) and the Mayo Clinic College of Medicine and Science in Rochester (USA). These results appeared in Cell (IF 66,85) have...[En savoir plus]

J. Mater Chem. C. [CLIC]

Abstract In this work diamino-porphyrin derivatives, in their free base or cobalt complex forms, have been used to construct SMJs. Porphyrin oligomers were covalently bonded to a bottom electrode by diazonium cation electroreduction and a STM tip was used to complete the junction. Conductance versus time (G(t)) measurements reveal stable SMJs with lifetimes as long as 70 s, attributable to the...[En savoir plus]

Chemistry – A European Journal [BCB / POMAM]

Abstract Cu-thiosemicarbazones have been intensively investigated for their application in cancer therapy or as antimicrobials. Copper(II)-di-2-pyridylketone-4,4-dimethyl-thiosemicarbazone (CuII-Dp44mT) showed anticancer activity in the submicromolar concentration range in cell culture. The interaction of CuII-Dp44mT with thiols leading to their depletion or inhibition was proposed to be...[En savoir plus]

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]

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]
