      The cover picture shows the role of Ag on the photocatalytic activity of TiO2. Ag0 particles on the surface of TiO2 hollow spheres enhance the transmission of photogenerated electrons, because metallic Ag has good conductivity. This delays the recombination of photoelectron–hole pairs and thus improves the photocatalytic activity. Details are discussed in the article by B. Li, L. Dong et al. on p. 1142 ff. For more on the story behind the cover research, see the Cover Profile.

    1. Olefin Metathesis

      Aryloxybenzylidene Ruthenium Chelates: Synthesis, Structure and Catalytic Activity in Olefin Metathesis (pages 1131–1136)

      Patrycja Żak, Szymon Rogalski, Maciej Kubicki, Piotr Przybylski and Cezary Pietraszuk

      Version of Record online: 29 OCT 2013 | DOI: 10.1002/ejic.201301208

      Thumbnail image of graphical abstract

      Ruthenium aryloxybenzylidene complexes have been synthesised and proved to behave like latent catalysts of olefin metathesis. The mechanism of chemical activation by HCl involves the formation of an isolable catalytically active hydroxybenzylidene complex.

    2. Nanoporous Iron Oxides

      Thermal Conversion of Hollow Prussian Blue Nanoparticles into Nanoporous Iron Oxides with Crystallized Hematite Phase (pages 1137–1141)

      Mohamed B. Zakaria, Ming Hu, Naoaki Hayashi, Yoshihiro Tsujimoto, Shinsuke Ishihara, Masataka Imura, Norihiro Suzuki, Yu-Yuan Huang, Yoshio Sakka, Katsuhiko Ariga, Kevin C.-W. Wu and Yusuke Yamauchi

      Version of Record online: 6 FEB 2014 | DOI: 10.1002/ejic.201301307

      Thumbnail image of graphical abstract

      Hollow Prussian blue nanoparticles are calcined under various reaction conditions to prepare nanoporous Fe oxides with a crystallized α-Fe2O3 (hematite) phase. The morphologies, surface areas, and degrees of crystallinity of the samples are varied by changing the number of hours of calcination. After calcination at 400 °C for 4 h, formation of a crystallized α-Fe2O3 phase is confirmed.

    1. Photocatalysts

      Preparation of Ag-Modified (B,P)-Codoped TiO2 Hollow Spheres with Enhanced Photocatalytic Activity (pages 1142–1149)

      Shuohan Yu, Bin Li, Yidan Luo, Lihui Dong, Minguang Fan and Feiyue Zhang

      Version of Record online: 6 FEB 2014 | DOI: 10.1002/ejic.201301388

      Thumbnail image of graphical abstract

      A Ag-modified (B,P)-codoped TiO2 hollow sphere catalyst was prepared through a sol–gel process with styrene–methyl methacrylate copolymer (PSMMA) microspheres as the template. The nonmetal dopants enhanced the light response of the catalyst, and the Ag played the role of photogenerated-electron transmitter. The catalyst exhibited high photocatalytic activity under UV light.

    2. Langmuir–Blodgett Films

      Ruthenium Acetate Cluster Amphiphiles and Their Langmuir–Blodgett Films for Electrochromic Switching Devices (pages 1150–1157)

      Amphiphilic triruthenium clusters containing a long-chain phenylazopyridine ligand are presented. Langmuir–Blodgett (LB) film formation and its electrochemical characterization are discussed. An LB film of the linear amphiphilic triruthenium cluster was applied for a near-IR (NIR) electrochromic switching device.

    3. Actinide Nanomaterials

      Thumbnail image of graphical abstract

      The synthesis of one-dimensional uranium-based nanostructures has been achieved by using electrodeposition technology with nanoporous polymer templates. The morphologies of uranyl hydroxide nanowires and nanotubes can be controlled by careful adjustment of the growth parameters. One-dimensional U3O8 nanostructures are also obtained through calcination of these nanowires and nanotubes.

    4. Gold

      Thumbnail image of graphical abstract

      Periodic arrays of gold atoms have been achieved with a helical columnar phase using a chiral cyclic trinuclear gold(I) complex. Columns are formed by complexes stacked at regular distances with a controlled orientation of the metallacycles along the columnar stack.

    5. Metal-Cased Cytotoxics

      Synthesis, Characterization and Cytotoxicity of (η6-p-cymene)ruthenium(II) Complexes of α-Amino Acids (pages 1174–1184)

      Folake A. Egbewande, Lydia E. H. Paul, Bruno Therrien and Julien Furrer

      Version of Record online: 23 JAN 2014 | DOI: 10.1002/ejic.201301297

      Thumbnail image of graphical abstract

      Reactions of [(η6-p-cymene)RuCl2]2 and amino acids (ratios 1:3–1:10) in the presence of AgCF3SO3 in D2O at 37 °C were carried out; these conditions mimic those of the cytosol. Stable bi- and tridentate chelate complexes were slowly generated and found to display a high degree of cytotoxicity against A2780 and A2780cisR cancer cell lines; cytotoxicities of these complexes exceed those of cisplatin.

    6. Metal Organic Frameworks

      Two Series of Lanthanide Metal-Organic Frameworks Constructed from Crown-Ether-Like Secondary Building Units (pages 1185–1191)

      Hao Wang, Rong-Mei Wen and Tong-Liang Hu

      Version of Record online: 23 JAN 2014 | DOI: 10.1002/ejic.201301324

      Thumbnail image of graphical abstract

      Lanthanide MOFs have been synthesized by using solvothermal reactions between 2,5-furandicarboxylic acid and KNO3 with the corresponding lanthanide nitrate. 1Ln (13) possesses a 3D network based on the “16-crown-6-like” secondary buildig unit (SBU), whereas 2Ln (48) exhibits a 1D framework with a “23-crown-9-like” SBU. Structural investigation unambiguously demonstrated that the lanthanide contraction affects the formation of 1Ln and 2Ln. Moreover, the luminescence intensity of 4 is sensitive to small molecules.

    7. Carbene Precursors

      Anatoliy Marchenko, Georgyi Koidan, Anastasiya Hurieva, Aleksandr Savateev, Alexander B. Rozhenko, Jean-Marc Sotiropoulos, Svitlana V. Shishkina, Oleg V. Shishkin and Aleksandr Kostyuk

      Version of Record online: 23 JAN 2014 | DOI: 10.1002/ejic.201301365

      Thumbnail image of graphical abstract

      Carbene precursor PIII and PV N-substituted formamidinium salts are obtained by the reaction of (di-tert-butylphosphanyl)amines and P,P-di-tert-butylphosphinoselenoic amides with Alder's dimer. The primary electrophilic attack of Alder's dimer proceeds at the phosphorus atom of the phosphanylamines or at the selenium atom of the phosphinoselenoic amides.

      Thumbnail image of graphical abstract

      The early stages of the reversed crystal growth of analcime (ANA) icositetrahedra were deeply studied by microwave-assisted hydrothermal synthesis with sodium carboxymethyl cellulose as a green template. Newly revealed intermediates were observed in some kinetically controlled stages, including hollow microsphere thin-shell nanoplatelets and self-assembled nanorods in the core of ANA.

    9. Bimetallic Complexes

      Alkane Elimination Reactions between Yttrium Alkyls and Tungsten Hydrides (pages 1211–1217)

      Adam P. Sobaczynski, Johannes Obenauf and Rhett Kempe

      Version of Record online: 27 JAN 2014 | DOI: 10.1002/ejic.201301476

      Thumbnail image of graphical abstract

      The alkane elimination reaction of [HW(CO)3Cp] (Cp = cyclopentadienyl) with various yttrium alkyls leads to multinuclear yttrium–tungsten complexes. Depending on the chosen yttrium alkyls and solvents, the nuclearity of the resulting compounds can be varied. Isocarbonyl linkage is the dominating interaction/bonding between the Y and W complex moieties.

    10. Phosphonio-Ylide Applications

      Version of Record online: 29 JAN 2014 | DOI: 10.1002/ejic.201301427

      Thumbnail image of graphical abstract

      New cationic and neutral compounds were obtained by treating phosphonioylide Ph3PCHP(O)Ph2 with MeI. The alkylated product can be deprotonated and gives an addition product with AlBr3. Product characterizations were carried out using 31P NMR spectroscopy and single-crystal X-ray diffraction analyses.

      A cationic phthalimido-functionalized N-heterocyclic carbene (NHC) palladium(II) complex has been prepared in high yield. The complex was activated instantly, without an initiation period, in the Suzuki–Miyaura cross-coupling reaction under benign aqueous aerobic conditions. Turnover frequencies (TOFs) up to 55000 h–1, were achieved with 0.01 mol-% of the complex.

      The synthesis of 4-(1-amino-5-aminotetrazolyl)methyleneimino-3-methylfuroxan from 3-methyl-4-formylfuroxan and 1,5-diaminotetrazole yields a thermally stable energetic compound. Its nitroiminotetrazole derivative exhibits high positive heats of formation and good detonation performance. Three nitrogen-rich energetic salts combine moderate thermal stabilities with acceptable sensitivities.
