Acta Crystallographica Section E, 2014 The title molecular salt, C5H7N2+·C12H8ClN4O7−·0.5H2O, crystallizes as a hemihydrate. The two rings in the barbiturate anion are not coplanar but make a dihedral angle of 43.17 (16)°. The two nitro groups deviate from the ring to which they are attached;

Rediscovering Sodium Ionophores as Selective Agents for Lithium Recognition and Extraction
Angewandte Chemie, EarlyView.Long‐classified sodium ionophores unexpectedly prefer lithium and act as efficient extractants in solid–liquid extraction (SLE). Readily prepared from catechol and haloacetamides, these hosts recover hydrated LiCl from multicomponent salt mixtures via a hydration‐assisted O···Li+ binding mode, enabling scalable lithium separation with Li/Na, Li/K, and ...

The anisotropic pi-effect of the nitro group in ammine-nitro cobalt(III) complexes
, 1997 The analysis of crystal structures of the series of ammine-nitro cobalt(III) complexes has shown that Co-NO2 bond lengths can be successfully rationalized on the basis of the anisotropic pi-effect of nitro groups. This effect governs both the orientation

Advanced Science, EarlyView.A nano‐confined radical anion acts as a photothermal immunogenic amplifier. Kinetically stabilized nanoparticles couple high near‐infrared‐II (NIR‐II) photothermal efficacy with glutathione (GSH) depletion to boost reactive oxygen species (ROS) and immunogenic cell death (ICD).

Asymmetric Iron‐Catalyzed Vicinal C(sp3)─H Diamination of Carboxylic Acids
Angewandte Chemie, EarlyView.An iron‐catalyzed vicinal α,β‐C(sp3)─H diamination of readily available carboxylic acids furnishes chiral α,β‐diamino acids in a single pot with high regio‐, diastereo‐, and enantioselectivity (up to >20:1 dr and >99% ee). ABSTRACT The direct construction of chiral 1,2‐diamines through the stereoselective functionalization of two vicinal C(sp3)─H bonds

Advanced Science, EarlyView.Rational engineering of terminal substituents in symmetric azobenzene‐based molecules enables precise control over conformationally coupled charge‐transfer processes. This design yields tunable nonvolatile resistive memory behaviors, ranging from write‐once‐read‐many‐times (WORM) to rewritable switching.
