      The cover picture shows metal complexes capable of cleaving DNA, so-called artificial metallonucleases. The DNA-cleaving agents presented in the Microreview by N. Kulak et al. on p. 2597 ff. are based on copper as the central atom and comprise N-donor ligands. Heteroaromatic, macrocyclic, and peptidic ligand systems (adumbrated in the background) are covered in detail. Whereas the focus of the Microreview is on the coordination chemistry of these artificial nucleases and the mechanism of DNA cleavage, potential applications in medicine and molecular biology are also briefly discussed. For more on the story behind the cover research, see the Cover Profile.

Molecular aggregates are deposited at the centers of terraces in a homogeneous distribution. In zero field, dynamic magnetic susceptibility measurements of powder samples of 1 show slow magnetic relaxation below 2 K.

    9. Luminescence

      Hierarchical Self-Assembly of Luminescent EuIII Complexes on Silicon (pages 2687–2694)

      Kasjan Misztal, Cristina Tudisco, Andrea Sartori, Joanna M. Malicka, Riccardo Castelli, Guglielmo G. Condorelli and Enrico Dalcanale

      Article first published online: 30 APR 2014 | DOI: 10.1002/ejic.201402117

      Thumbnail image of graphical abstract

      Supramolecular complexes on a silicon surface exhibit red luminescence under UV irradiation. A hierarchical self-assembly procedure for the generation of luminescent ternary complexes on surfaces is reported. It relies on orthogonal host–guest interactions of tetraphosphonate cavitands toward sarcosine and on the metal–ligand coordination of phenanthroline with lanthanide complexes.

    10. Luminescent Complexes

      Series of O,N,O-Tridentate Ligands Zinc(II) Complexes with High Solid-State Photoluminescence Quantum Yield (pages 2695–2703)

      Silver particles with nanostructured spiky morphologies have been obtained by two different wet-synthesis approaches. A detailed investigation was carried out into the synthesis parameters to tune the final particle shape. The spiky particles were used as conductive fillers in piezoresistive composites to demonstrate the enhancing effect of the sharp tips on tunneling conduction phenomena.

    13. Photochemistry

      Anchor-Functionalized Push-Pull-Substituted Bis(tridentate) Ruthenium(II) Polypyridine Chromophores: Photostability and Evaluation as Photosensitizers (pages 2720–2734)

      Aaron Breivogel, Sanghyuk Wooh, Jan Dietrich, Tea Yon Kim, Yong Soo Kang, Kookheon Char and Katja Heinze

      Article first published online: 28 APR 2014 | DOI: 10.1002/ejic.201402091

      Thumbnail image of graphical abstract

      A remarkable photostability of ruthenium(II) sensitizers in the presence of iodide and water is achieved by a bis(tridentate) coordination. The pronounced donor–acceptor substitution in the heteroleptic complexes shifts the absorption maxima to low energy, with λmax = 544 nm extending to 720 nm. The sensitizers were introduced into dye-sensitized solar cells and their performance was compared to that of the standard N719 dye.
