      The cover picture shows the formation of one-dimensional nanochains of silver nanoparticles (AgNPs) upon addition of a polyamine molecular linker. In the present work, the binding ability of this linker was exploited, bearing different functional groups, which favors the self-assembly of silver and gold nanoparticles (AuNPs) into one-dimensional nanochains in aqueous solution. These nanochains visually resemble the artistic work of “calceteiros” (pavers) to build the “calçada Portuguesa” (Portuguese pavements) in Portugal (Photography “calçada Portuguesa”, Jose M. G. Pereira). Polyamine ligands are very versatile materials due to their water solubility and flexibility. The study of AgNPs and AuNPs in one-dimensional nanostructured formations are finally used as new sophisticated heavy metal (Hg2+) ion chemosensors. For more details, see the Full Paper by Carlos Lodeiro, Christina Núñez and co-workers, on p. 200 ff.

      This collaboration started nearly 15 years ago with the purpose to use the expertise in the synthesis of polyamine acyclic and macrocyclic ligands and derivatives of the group at Santiago de Compostela, and the skills in nanochemistry and photophysical studies of the BIOSCOPE group for the development of new fluorescent nanostructured chemosensors.” More about the story behind the cover research can be found on p. 200.

      Metallocyclodextrins: Combining Cavitands with Metal Centres (pages 176–179)

      Dr. Rafael Gramage-Doria

      Version of Record online: 28 AUG 2013 | DOI: 10.1002/open.201300033

      Thumbnail image of graphical abstract

      Non-conventional coordination chemistry occurs upon encapsulation of metal fragments in the cavity of a β-cyclodextrin-derived diphosphane (WIDEPHOS). It was found possible to form otherwise unstable metal species and slow down coordination processes, allowing the elucidation of novel mechanistic pathways for carbon[BOND]carbon bond-forming reactions.

      Non-ATP-Mimetic Organometallic Protein Kinase Inhibitor (pages 180–185)

      Version of Record online: 5 SEP 2013 | DOI: 10.1002/open.201300031

      Non-hinge binding: A novel organometallic protein kinase inhibitor scaffold based on a cyclometalated 1,8-phenanthrolin-7(8 H)-one ligand is reported, which binds to the ATP binding site of the protein kinase Pim1 in an unexpected, unusual non-ATP-mimetic fashion without mimicking the hydrogen-bonding interaction of the adenine nucleobase of ATP.

      B-DNA Structure and Stability as Function of Nucleic Acid Composition: Dispersion-Corrected DFT Study of Dinucleoside Monophosphate Single and Double Strands (pages 186–193)

      Bonds and order: The stability of the B-DNA double helix is shown (see illustration), based on dispersion-corrected density functional computations, to depend not only on the number of hydrogen bonds in Watson–Crick base pairs but also on the order and orientation in which these base pairs occur.

      Solid-State-Trapped Reactive Ammonium Carbamate Self-Derivative Salts of Prolinamide (pages 194–199)

      Trapped within: We report single-crystal characterization of polymorphs of the ammonium carbamate self-derivative salt of prolinamide, and the first crystal structure of prolinamide and of derived products. This study emphasizes the reactivity of carbonated amines in the solid state and opens perspectives for a systematic study of (solid-state) reactions involving these trapped reactive species.

      1D Nanochain formation: The binding ability of a polyamine molecular linker (L)2− bearing different functional groups, which favors the self-assembling of silver (AgNPs) and gold nanoparticles (AuNPs) into 1D nanochains in aqueous solution was explored. UV/Vis spectrophotometry and TEM were used to determine time-dependent structural changes associated with these 1D structure formations. Sensing of Hg2+ using AgNPs@(L)2− and AuNPs@(L)2− assemblies was also carried out in aqueous solution.

      Version of Record online: 26 JUL 2013 | DOI: 10.1002/open.201300022

      Thumbnail image of graphical abstract

      Simple and effective: A facile procedure for monitoring chemical reactions and characterizing compounds dissolved in ionic liquids is described using the MS/MS technique. Separation of species of interest was carried out using internal electronic gate available in electrospray mass spectrometers, instead of chromatography and extraction. The separation was carried out as a fast (milliseconds) and sustainable (no extra solvents) procedure.
