With growing interest in the function and properties of natural lipid bilayers, synthetic liposomes have been intensively studied for several decades and many artificial systems have been designed to mimic natural cell membranes. An important concept for this is the embedding of synthetic amphiphiles into vesicular bilayers. The dynamic nature of the noncovalent assemblies obtained this way allows the rapid and simple development of bio-inspired responsive nanomaterials, which can be applied for molecular recognition, sensor systems, and the development of reactive interfaces. For more information see the Concept article by B. König and B. Gruber on page 438 ff.

Anionic N-Heterocyclic Carbene Ligands

In their Communication on page 450 ff., A. Danopoulos, K. Yu. Monakhov and P. Braunstein examine new ways for fine-tuning and expanding the coordination chemistry of carbene ligands. Deprotonation/lithiation of mesoionic 4-aryliminoimidazolium precursors afforded anionic N-heterocyclic carbene (NHC) ligands bearing a remote anionic amido functionality. The preference for binding to Li+, [Li(tmeda)]+, AgI, and FeII is examined with respect to the remote anionic-amido–neutral NHC versus the remote neutral-imino–anionic imidazol-2-ylidene-ide forms. DFT calculations demonstrate that tuneable electronic and steric factors of the substituent at the Nexo atom of the heterocycle dictate the preferred site of the metallation.

A template-free solvothermal method has been developed to synthesize hierarchical V-glycolate hollow microspheres, which can be easily transformed to hierarchical V2O5 hollow microspheres with a well-maintained structure. When used as cathode materials for lithium-ion batteries, these hierarchical V2O5 hollow spheres show remarkable electrochemical performance with excellent rate capability and cycling stability. For more information see the Full Paper by X. W. Lou et al. on page 494 ff.
