      The cover picture shows a human in an activity that can potentially trigger asthma or heart attacks. These attacks involve blood-vessel contraction and are therefore typically indicated in advance by an increase in NO concentration in the exhaled air. Fundamental work on photonic sensing of NO via reversible binding to an amphiphilic iron(III) corrole complex is reported. Details are given in the Full Paper by M. Presselt et al. on page 594 in Issue 7, 2016 (DOI: 10.1002/cplu.201500553).

    1. Disassembly of Chromophore-Guided DNA Duplexes through Site-Selective Binding of Coralyne to Pyrene-Modified Adenine Bases (pages 590–593)

      Dr. Ki Tae Kim, Tae Su Choi, Ka Young Kim, Prof. Dr. Hugh I. Kim and Prof. Dr. Byeang Hyean Kim

      Intercalation for separation: Disassembly of chromophore-guided DNA assemblies carried out under ambient temperature has been achieved through intercalative binding of coralynes to pyrene-modified adenine (PyA) bases (see figure). This behavior, which is opposite to that of coralyne-induced self-duplex formation of natural oligodeoxyadenylates, was applied to prepare new types of coralyne-stimulated switchable DNA modules.

      NO hiding from this sensor: Reversible binding of nitric oxide to an iron(III) corrole induces spectral changes close to the Soret absorption band, thus enabling photometric nitric oxide detection (see figure). Sensitive photometric detection in the picomolar range was possible using this amphiphilic iron(III) corrole. The amphiphilicity allows for self-assembly of the complex into thin solid films, which will be developed for sensing applications.

    2. DNA Intercalators for Detection of DNA Hybridisation: SCS(MI)–MP2 Calculations and Electrochemical Impedance Spectroscopy (pages 604–612)

      Daliborka Jambrec, Dr. Raoudha Haddad, Anna Lauks, Dr. Magdalena Gebala, Prof. Dr. Wolfgang Schuhmann and Dr. Malte Kokoschka

      Version of Record online: 6 JUN 2016 | DOI: 10.1002/cplu.201600173

      A model sandwich: The prediction of interaction energies using quantum mechanical SCS(MI)–MP2/cc-pVTZ calculations is presented. These calculations can be used to predict the strength of interactions between intercalators and DNA, allowing the evaluation of the probability of intercalation and the selectivity for dsDNA. Electrochemical impedance spectroscopy was used for comparison and the experimental results are in good agreement with the calculated predictions.

    3. Synthesis, Optical, Electrochemical, and Theoretical Studies of Dipolar Ruthenium Alkynyl Complexes with Oligo(phenylenevinylene) Bridges (pages 613–620)

      Huihua Zhang, Dr. Mahbod Morshedi, Mahesh S. Kodikara, Dr. Graeme J. Moxey, Dr. Genmiao Wang, Huan Wang, Cristóbal Quintana, Em. Prof. Rob Stranger, Prof. Chi Zhang, Prof. Marie P. Cifuentes and Prof. Mark G. Humphrey

      Crossing bridges: For end-functionalized oligo(p-phenylenevinylene)s (OPVs) with a donor-ligated ruthenium centre and acceptor nitro group (see figure), oxidation potentials and wavelength of the UV/Vis λmax band plateau and quadratic nonlinearities are maximized around the complex with a tri(phenylenevinylene) unit. Computational studies suggest that intra-OPV rotations result in the experimentally observed, relatively invariant properties for the higher OPV examples.

    4. Syntheses and Optical Properties of Azo-Functionalized Ruthenium Alkynyl Complexes (pages 621–628)

      Dilan Wei, Mahesh S. Kodikara, Dr. Mahbod Morshedi, Dr. Graeme J. Moxey, Huan Wang, Dr. Genmiao Wang, Cristóbal Quintana, Prof. Chi Zhang, Em. Prof. Rob Stranger, Prof. Marie P. Cifuentes and Prof. Mark G. Humphrey

      It takes alkynes: Dipolar organometallic complexes with a ligated ruthenium donor, nitro acceptor, and a π-delocalizable bridge incorporating an azo group exhibit large quadratic optical nonlinearities (see figure). The potentials of their reversible oxidation processes and the wavelengths of their absorption maxima in both the resting and oxidized forms are tuned by systematic structural modification.

    5. Amphiphilic Carbonaceous Microsphere-Stabilized Oil-in-Water Pickering Emulsions and Their Applications in Enzyme Catalysis (pages 629–636)

      Dr. Li Liu, Linlin Jiang, Xiaomin Xie and Assoc. Prof. Sen Yang

      Version of Record online: 15 JUN 2016 | DOI: 10.1002/cplu.201600127

      Drop everything: An oil-in-water Pickering emulsion system stabilized by carbonaceous microspheres was prepared and successfully used in a lipase-catalyzed hydrolysis reaction (see figure). More than 99 % of the lipase was adsorbed at the interface layer of emulsion droplets and showed excellent stability and activity. The oil-in-water Pickering emulsion system shows the great potential and advantages for use in enzyme-catalyzed hydrolysis reactions.

    6. Study of Red-Emission Piezochromic Materials Based on Triphenylamine (pages 637–645)

      Seeing red: Two conjugated molecules based on triphenylamine (TPA) and 1,3-indandione (IND) are prepared by employing Suzuki cross-coupling reaction and Knoevenagel condensation. Both materials demonstrate red emission, aggregation-induced emission behavior, and solvatochromic and piezochromic properties. These red luminescence materials are able to respond to fluoride and iodide in THF sensitively (see figure; TPAT=5-(4-diphenylaminophenyl)thiophene-2-carbaldehyde).

    7. Facile Synthesis of Fe3C@Graphene Hybrid Nanorods as an Efficient and Robust Catalyst for Oxygen Reduction Reaction (pages 646–651)

      Controlled coating: Fe3C@graphene catalysts for the oxygen reduction reaction (ORR) have been prepared from agar, urea, and Fe2O3 nanorods. These materials show better ORR activity and stability than the commercial Pt/C catalyst.

    8. Folate-Conjugated Polylactic Acid–Silica Hybrid Nanoparticles as Degradable Carriers for Targeted Drug Delivery, On-Demand Release and Simultaneous Self-Clearance (pages 652–659)

      Dr. Zhifang Ma, Dr. Xiaolei Li, Xiaodan Jia, Dr. Jing Bai and Prof. Xiue Jiang

      Version of Record online: 2 JUN 2016 | DOI: 10.1002/cplu.201600100

      Wait before removing your coat: A novel SiO2-based nanocarrier coated with polylactic acid and folate (FA) has been used to destroy tumors (see figure). This nanocomposite can target the delivery of doxorubicin (Dox) without premature leakage of the drug before the polylactic acid is degraded. Decomposition of the SiO2 carrier improves its clearance from biological tissues.

    9. Aminocyclodextrin Oligomers as Protective Agents of Protein Aggregation (pages 660–665)

      Version of Record online: 7 JUN 2016 | DOI: 10.1002/cplu.201600239

      Keep away from each other! Aminocyclodextrin oligomers were synthesized and their ability to inhibit the aggregation of amyloid proteins was compared to that of unfunctionalized oligomers or polymers. Aggregation of Aβ protein was inhibited at micromolar concentrations, and significantly, the oligomers were not cytotoxic. The presence of both a multicavity system and amino groups seems to have a key role in the antiaggregant activity.
