ChemPlusChem 3/2015: Materials-Based Research

ChemPlusChem 3/2015: Materials-Based Research

A floating photocatalyst consisting of polyurethane foam (PUF) coated with well-ordered mesoporous TiO2 has been developed by Zipeng Xeng for the treatment of dye wastewater. Organic--inorganic hybrid materials with amino groups as basic sites were devised by Maksym Opanasenko, who is also featured in our Early Career Series. These layered zeolitic materials display high activity in the Knoevenagel condensation of benzaldehyde and malononitrile and hold promise as basic heterogeneous catalysts. Finally, in the article featured on the cover, David Cornu studies the effect of the orientation of electrospun carbon fibers on their properties as bioelectrodes. He and his research group are also featured in the cover profile of this issue. We wish you stimulating reading!

  1. Toward the Prediction of Activity in the Ethylene Polymerisation of ansa-Bis(indenyl) Zirconocenes: Effect of the Stereochemistry and Hydrogenation of the Indenyl Moiety

    Dr. Iván Bravo, Dr. Carlos Alonso-Moreno, Dr. Fernando Carrillo-Hermosilla, Dr. Isabel López-Solera, Dr. Antonio Antiñolo and Dr. José Albaladejo

    Article first published online: 3 MAR 2015 | DOI: 10.1002/cplu.201500008

    Fine-tuning: A combination of experimental and quantum studies on rac- and meso-ansa-bis(indenyl) zirconocene catalysts supports experimental data obtained in ethylene polymerization (see figure). The rac isomer has a higher activity than the meso counterpart, whereas hydrogenation of the six-membered ring leads to an increase in the activity of the rac form.

  2. Click Reaction as a Tool to Combine Pharmacophores: The Case of Vismodegib

    Michael S. Christodoulou, Mattia Mori, Rebecca Pantano, Romina Alfonsi, Paola Infante, Maurizio Botta, Giovanna Damia, Francesca Ricci, Panagiota A. Sotiropoulou, Sandra Liekens, Bruno Botta and Daniele Passarella

    Article first published online: 27 FEB 2015 | DOI: 10.1002/cplu.201402435

    Mix and Click! Rational design, versatile synthesis, and biological evaluation of Vismodegib analogues has been achieved to confirm the 1,2,3-triazole ring as a creative tool to combine pharmacophores. Interaction with the Hedgehog pathway and the ability to inhibit the formation of blood vessels are discussed (see figure).

  3. Temperature-Dependent Immobilization of a Tungsten Peroxo Complex That Catalyzes the Hydroxymethoxylation of Olefins

    Jizhong Chen, Dr. Li Hua, Chen Chen, Li Guo, Ran Zhang, Angjun Chen, Yuhe Xiu, Xuerui Liu and Prof. Zhenshan Hou

    Article first published online: 27 FEB 2015 | DOI: 10.1002/cplu.201402456

    Thumbnail image of graphical abstract

    Running hot and cold: A tungsten peroxo complex (see picture) can dissociate and diffuse into the liquid phase at the reaction temperature, resulting in a homogeneous reaction. After reaction, the catalytically active species was anchored on the functionalized silica by hydrogen-bonding as the temperature was lowered to 0 oC. This offers an effective approach for catalyst recovery and recycling.

  4. Synthesis, Physicochemical Characterization, and Interaction with DNA of Long-Alkyl-Chain Gemini Pyridinium Surfactants

    Dr. Nadia Barbero, Claudio Magistris, Dr. Pierluigi Quagliotto, Luca Bonandini, Dr. Claudia Barolo, Dr. Roberto Buscaino, Dr. Carlotta Compari, Laura Contardi, Prof. Emilia Fisicaro and Prof. Guido Viscardi

    Article first published online: 27 FEB 2015 | DOI: 10.1002/cplu.201500007

    Bringing it all together: This study on gemini pyridinium surfactants (see figure) contributes to the knowledge about the aggregation behavior of these compounds and their interactions with biological molecules. Structure–activity relationships were found in the context of the physico-chemical properties of these compounds and DNA compaction. These insights should improve the understanding of surfactant-based gene delivery.

  5. Three-Dimensional Arrays of 1D MnO2 Nanocrystals for All-Solid-State Asymmetric Supercapacitors

    Deepak P. Dubal, Rudolf Holze and Pedro Gomez-Romero

    Article first published online: 27 FEB 2015 | DOI: 10.1002/cplu.201500054

    Thumbnail image of graphical abstract

    New builders on the block: The synthesis of 3D hierarchical structures based on 1D MnO2 nanobuilding blocks by means of a facile and scalable coprecipitation method and their use as electrodes for the assembly of all-solid-state supercapacitors is described. The figure show an example of an asymmetric device based on hierarchical nanoneedle (Nn)-like MnO2 and reduced graphene oxide.
