      The cover picture outlines the formation of 5-cyanotetrazole from sodium azide and sodium cyanide, which can be further converted into its hydrolysis products tetrazole-5-carboxamide and tetrazole-5-carboxamide oxime. Both products were deprotonated to form the respective hydroxylammonium salts. Among other nitrogen-rich salts of tetrazole-5-carboxamide oxime, they were structurally characterized. The silver salt of 5-cyanoetetrazole is an example of rarely described crystal structures of silver tetrazolate salts. A full account can be found in the Full Paper by T. Klapötke and co-workers on page 877 ff.

      Magnetic cleansing: A magnetic Fe3O4–Co catalyst was prepared using inexpensive precursors and its catalytic activity was tested for the oxidation of alcohols using tert-butyl hydroperoxide (TBHP) as the oxidant. The corresponding carbonyl compounds were obtained in good to excellent yields (see scheme); furthermore, this magnetic catalyst could be separated by magnetic decantation without significant loss in activity.

      SMM SAMs: The magnetic properties of bis(phthalocyaninato)terbium(III) complexes [Tb{Pc′(SR)8}2] bearing eight peripheral alkylthio substituents SR (R=n-C8H17, n-C12H25; see figure) were studied by SQUID measurements. These highly soluble single-molecule magnets were self-assembled from solution onto solid gold substrates and the self-assembled monolayers characterised by XPS, NEXAFS and AFM measurements.

    3. Structure-Directing L-Tryptophan for Supported DPPC Helices and Fractals: An Alkyl-Chain Tilt-Angle Dependence (pages 898–907)

      Nirod Kumar Sarangi and Prof. Archita Patnaik

      Version of Record online: 13 JUL 2012 | DOI: 10.1002/cplu.201200075

      Helix control: Supported 1D lipid helices of dipalmitoylphosphatidylcholine from interfacial and trans-membrane L-tryptophan interactions are reported. A diversity of interactions such as insertion, folding, dipole reorientation, steric interactions and molecular tilt dependence are invoked (see figure). Molecular dynamics simulations succinctly corroborate the induction of helicity into a nonhelical lipid, implying that trans-membrane tryptophans support such segmental interactions.

    4. A Reaction-Based Colorimetric Fluoride Probe: Rapid “Naked-Eye” Detection and Large Absorption Shift (pages 908–913)

      Xiaohong Cheng, Shuang Li, Guohua Xu, Conggang Li, Prof. Jingui Qin and Prof. Zhen Li

      Version of Record online: 17 JUL 2012 | DOI: 10.1002/cplu.201200106

      Seen with the naked eye: A new ratiometric colorimetric probe toward fluoride has been designed based on the fluoride-promoted cleavage of the Si[BOND]O bond by using intramolecular charge transfer as a signaling mechanism. Upon the addition of F, the probe changes color from colorless to deep blue and is visible with the naked eye. This change is accompanied by a dramatic shift of the maximum absorption wavelength (≈230 nm; see scheme).

    5. Layer-By-Layer Self-Assembly of Sulphydryl-Functionalized Multiwalled Carbon Nanotubes and Phosphate-Functionalized Gold Nanoparticles: Detection of Hydrazine (pages 914–922)

      Layer upon layer: Based on Au[BOND]S bond interactions between MWCNT-SH and AuP–NPs, the all-solid-state multilayered nanostructures of MWCNT/AuP–NPs are readily formed by the LBL method (see figure). The nanostructures possess excellent electrocatalytic activity toward N2H4 oxidation. In the synthetic route, AuP–NPs in multilayered films retain their “clean” surface active sites, making it attractive for application in heterogeneous catalysis, fuel cells, and electrochemical biosensor.

      On the move: A series of dithienylthiazolo[5,4-d]thiazole (DTTzTz) semiconductors has been synthesized and investigated as active materials in solution-processed organic field-effect transistors. Spin-coated films of one of the derivatives showed a micrometer scale fibrillar texture and high field-effect mobilities (10−3 cm2 V−1 s−1) were observed. This molecule represents the first example of a highly soluble DTTzTz-based small organic compound for which reasonable FET behavior was observed.

    7. Facile Synthesis of an Ag2O–ZnO Nanohybrid and Its High Photocatalytic Activity (pages 931–935)

      Ming Wu, Dr. Jun-Min Yan, Dr. Ming Zhao and Dr. Qing Jiang

      Version of Record online: 31 JUL 2012 | DOI: 10.1002/cplu.201200159

      Be active! A facile, basic coprecipitation-assisted hydrothermal strategy has been employed to prepare an Ag2O–ZnO (0.3:0.7) nanohybrid. The nanohybrid shows excellent photocatalytic properties for degradation of rhodamine B, even under visible light irradiation. This effect is much better than pure or a physical mixture of Ag2O and ZnO (see graph).

    8. Synthesis and Electrocatalytic Properties of Palladium Network Nanostructures (pages 936–940)

      Guojie Zhang, Lu Zhang, Liping Shen, Dr. Yu Chen, Yiming Zhou, Dr. Yawen Tang and Tianhong Lu

      Version of Record online: 21 AUG 2012 | DOI: 10.1002/cplu.201200163

      It's all about networking: Palladium network nanostructures (Pd NNSs; B in figure) have been prepared by facile reduction of K2PdIICl4/K4FeII(CN)6 cyanogel (A); this approach is template-free and organic-molecule-free. The size, morphology, surface composition, and electrochemical properties of this three-dimensional network were studied. Pd NNSs show high electrocatalytic activity toward electrooxidation of formic acid.
