      The preparation of a new Mo6 cluster complex that exhibits oxygen-sensitive red luminescence (ΦL = 1) associated with efficient singlet oxygen production (ΦΔ = 0.85) and good absorption in the visible region brings a relevant alternative to the dyes and sensitizers so far used. This is illustrated by the design of composite materials useful for optical oxygen sensing and singlet oxygen sensitizing.

      Iridium–carbon sigma bond formation in supercages of faujasite-type zeolites is achieved by using a microwave-assisted ship-in-a-bottle synthesis. The successive reaction of IrIII cations in the zeolite with two ligands leads to two types of complexes in the different supercages, and the emission from these IrIII complexes can be tuned in a range from blue to green.

    2. Polynuclear Copper(II) Complexes

      fac-[Re(NSO)(CO)3] complexes were synthesized with varying chelate ring size and geometry. The order of complex formation preference is: linear (6,5-membered rings) > tripodal (6,5,7-membered rings) > linear (two six-membered rings). The analogous fac-[99mTc(NSO)(CO)3] complexes were prepared in high yield and were stable in solution.

    4. CO-Releasing Molecules

      A Comparative Study of Tricarbonylmanganese Photoactivatable CO Releasing Molecules (PhotoCORMs) by Using the Myoglobin Assay and Time-Resolved IR Spectroscopy (pages 3140–3146)

      Wilhelm Huber, Rolf Linder, Johanna Niesel, Ulrich Schatzschneider, Bernhard Spingler and Peter C. Kunz

      Version of Record online: 23 MAY 2012 | DOI: 10.1002/ejic.201200115

      CO-releasing molecules are interesting therapeutic agents that can deliver and release CO upon stimulation. Light triggers the release of CO in different complexes [LMn(CO)3]+, where L is an N,N,N ligand. Although different amounts of CO released per complex are observed by myoglobin assay, IR spectroscopic investigation of their solutions indicates loss of all CO ligands.

    5. Enzyme Mimics

      Marianne Wenzel and Eric Meggers

      Version of Record online: 10 MAY 2012 | DOI: 10.1002/ejic.201200203

      Thumbnail image of graphical abstract

      (Mercaptophenyl)oxazolines were used as chiral auxiliaries for the asymmetric synthesis of polypyridyl ruthenium complexes. Key step was the conversion of a coordinated thiolate into a labilized thioether upon methylation with Meerwein salt, followed by a thermal substitution with an achiral ligand under retention of configuration.

    8. SERS-Active Substrates

      Multifunctional TiO2-Coated Ag Nanowire Arrays as Recyclable SERS Substrates for the Detection of Organic Pollutants (pages 3176–3182)

      Ying Zhou, Jin Chen, Li Zhang and Liangbao Yang

      Version of Record online: 16 MAY 2012 | DOI: 10.1002/ejic.201200009

      Thumbnail image of graphical abstract

      A novel method to prepare TiO2-coated Ag nanowire arrays for use as multifunctional surface-enhanced Raman scattering (SERS) active substrates is introduced. Employing this substrate for the detection of organic contaminants can lead to high SERS enhancement. Owing to the high photocatalytic activity of TiO2, the substrate can degrade target molecules into small inorganic molecules, and in this way the arrays are able to self-clean.

      From dimers to monomers by oxidative addition: The alkoxido-bridged dimeric tin(II) compound 3 undergoes oxidative addition by the reaction with bromine to give compound 7 that in turn is monomeric by an additional intramolecular N[RIGHTWARDS ARROW]Sn interaction. The methoxy-substituted analogue 8, however, is a dimer.

    11. Visible Light Photocatalysis

      In Situ Photoactivated AgCl/Ag Nanocomposites with Enhanced Visible Light Photocatalytic and Antibacterial Activity (pages 3200–3208)

      Lihong Dong, Dadong Liang and Ruchun Gong

      Version of Record online: 22 MAY 2012 | DOI: 10.1002/ejic.201200172

      Thumbnail image of graphical abstract

      AgCl/Ag nanocomposites were fabricated by a simple photoactivation process. A uniform layer of Ag nanoparticles (5–10 nm) was formed on the surface of AgCl nanoparticles (50–100 nm) by irradiation with a fluorescent lamp or direct sunlight. The AgCl/Ag nanocomposites show higher visible light photocatalytic activity for decomposing organic pollutants under the irradiation of common fluorescent lamp or direct sunlight. They also show better antibacterial properties.

    12. Cyclometalated Ir Complexes

      Bis(pyrazol-1-yl)methane as Non-Chromophoric Ancillary Ligand for Charged Bis-Cyclometalated Iridium(III) Complexes (pages 3209–3215)

      Sheng Meng, Il Jung, Jie Feng, Rosario Scopelliti, Davide Di Censo, Michael Grätzel, M. Khaja Nazeeruddin and Etienne Baranoff

      Version of Record online: 18 MAY 2012 | DOI: 10.1002/ejic.201200197

      Thumbnail image of graphical abstract

      The bis(pyrazol-1-yl)methane ancillary ligand induces a blueshift in the emission of charged cyclometalated iridium(III) complexes. In addition, the nonradiative rate constant increases by one order of magnitude when the ligand is substituted with methyl groups, which induce some steric hindrance and lead to a more loosely bound ancillary ligand.

    13. Silicon Pentacoordination

      Neutral Pentacoordinate Halogeno- and Pseudohalogenosilicon(IV) Complexes with a Tridentate Dianionic O,N,O or N,N,O Ligand: Synthesis and Structural Characterization in the Solid State and in Solution (pages 3216–3228)

      Version of Record online: 23 MAY 2012 | DOI: 10.1002/ejic.201200308

      Thumbnail image of graphical abstract

      A series of neutral pentacoordinate silicon(IV) complexes was synthesized and structurally characterized by NMR spectroscopy (solid state and solution) and single-crystal X-ray diffraction. The compounds studied contain a tridentate dianionic O,N,O or N,N,O ligand, a phenyl ligand, and a (pseudo)halogeno ligand (F, Br, CN, N3, NCS). These complexes were compared with related compounds that contain a tridentate dianionic S,N,O ligand.

    14. Polyoxometalates

      Assembly of Saturated Nb/W Mixed-Addendum Polyoxometalate [P2W15Nb3O62]9– and Lanthanide Ions (Ln = Eu, Ce) (pages 3229–3234)
