Prize-winning chemistry!

The Nobel Prize in Chemistry 2014 has been awarded jointly to Eric Betzig, Howard Hughes Medical Institute, Ashburn, VA, USA, Stefan W. Hell, Max Planck Institute for Biophysical Chemistry, Göttingen, and German Cancer Research Center, Heidelberg, Germany, and William E. Moerner, Stanford University, CA, USA, "for the development of super-resolved fluorescence microscopy".

Work from Stefan Hell and his group on masked rhodamine dyes and their applications in light microscopy applications was recently highlighted on the front cover of Chemistry—A European Journal.

  1. B(C6F5)3-Mediated Transformations and Hydrogenation of Carbodiimides

    Dr. Michael H. Holthausen, Mariah Colussi and Prof. Dr. Douglas W. Stephan

    Article first published online: 26 NOV 2014 | DOI: 10.1002/chem.201405014

    Frustrated Lewis pairs: Reactions of carbodiimides (RN[DOUBLE BOND]C[DOUBLE BOND]NR) with B(C6F5)3 yield either four-membered boron amidinate heterocycles or cyanamide derivatives depending on the nature of the substituents. In the presence of dihydrogen, mixtures of RN[DOUBLE BOND]C[DOUBLE BOND]NR and B(C6F5)3 are amenable to stepwise hydrogenation. The reaction with one or two equivalents of H2 yields amidine or amidinium borate-type products, respectively (see scheme).

  2. Tuning the Spin-Crossover Behaviour of a Hydrogen-Accepting Porous Coordination Polymer by Hydrogen-Donating Guests

    Jin-Yan Li, Yan-Cong Chen, Ze-Min Zhang, Wei Liu, Dr. Zhao-Ping Ni and Prof. Ming-Liang Tong

    Article first published online: 26 NOV 2014 | DOI: 10.1002/chem.201405060

    Abrupt or stepped spin crossover behaviours with thermal hysteresis are observed on exchanging a range of protic solvents into a porous Hoffman-like coordination polymer with uncoordinated pyridyl groups that act as H-accepting sites for guest–host hydrogen-bonding interactions. The critical temperatures of the various solvates can be tuned across a range of about 130 K (see figure).

  3. Porous Carbon Anodes for a High Capacity Lithium-Ion Battery Obtained by Incorporating Silica into Benzoxazine During Polymerization

    Dr. De-Cai Guo, Dr. Fei Han and Prof. Dr. An-Hui Lu

    Article first published online: 26 NOV 2014 | DOI: 10.1002/chem.201405068

    Porous carbons with controllable Vmes/Vmic ratios can be obtained through a poly(benzoxazine-co-resol) system. A correlation between the capacity and Vmes/Vmic ratio has been established, which shows a high reversible capacity of 660 mAh g−1 in the porous carbon with high Vmes/Vmic ratio, due to the good accessibility of Li ions to active sites provided by the micropores.

  4. Theoretical Study on the Relationship between Diradical Character and Second Hyperpolarizabilities of Four-Membered-Ring Diradicals Involving Heavy Main-Group Elements

    Hiroshi Matsui, Kotaro Fukuda, Shota Takamuku, Prof. Dr. Akira Sekiguchi and Prof. Dr. Masayoshi Nakano

    Article first published online: 26 NOV 2014 | DOI: 10.1002/chem.201404592

    Relationship issues: The relationship between the diradical character (y) and second hyperpolarizability (γ; third-order nonlinear optical property) for several four-membered-ring diradicals involving heavy main-group elements was investigated (see figure). It is found that γ is enhanced in the intermediate y region, and that the y and γ can be controlled by modifying the main-group elements and the donor/acceptor groups substituted into the four-membered ring.

  5. Silver/Gold Core–Shell Nanoprism-Based Plasmonic Nanoprobes for Highly Sensitive and Selective Detection of Hydrogen Sulfide

    Dr. Xinjian Yang, Yuqian Ren and Dr. Zhiqiang Gao

    Article first published online: 26 NOV 2014 | DOI: 10.1002/chem.201405012

    Thumbnail image of graphical abstract

    Plasmonic nanoprobes: Plasmonic Ag/Au core–shell nanoprism nanoprobes are demonstrated for the detection of hydrogen sulfide based on the strong ability of hydrogen sulfide to etch the Ag/Au core–shell nanoprisms. In the presence of hydrogen sulfide, silver in the nanoprisms is converted to Ag2S at the defective lateral walls, accompanied by an obvious surface plasmon resonance (SPR) absorption depression and peak shift (see figure).
