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.

- Structure–Property Relationship of Supramolecular Ferroelectric [H-66dmbp][Hca] Accompanied by High Polarization, Competing Structural Phases, and Polymorphs
Dr. Kensuke Kobayashi, Dr. Sachio Horiuchi, Dr. Shoji Ishibashi, Dr. Fumitaka Kagawa, Prof. Youichi Murakami and Prof. Reiji Kumai

A positive relationship between the phase-transition temperature (TC) and hydrogen-bond length was observed. The optimized spontaneous polarization (Ps) agreed well with the results of the first-principles calculations. The experimental and theoretical data consistently demonstrated that stretching the hydrogen-bond length is a promising way to enhance the polarization performance and thermal stability of hydrogen-bonded organic ferroelectrics (see figure).
- NHCSiCl4: An Ambivalent Carbene-Transfer Reagent
Dr. Tobias Böttcher, Simon Steinhauer, Dr. Lesley C. Lewis-Alleyne, Beate Neumann, Dr. Hans-Georg Stammler, Dr. Bassem S. Bassil, Prof. Dr. Gerd-Volker Röschenthaler and Prof. Dr. Berthold Hoge

One way or another: NHCSiCl4 is not only a carbene-transfer reagent that is useful for the synthesis of p-block complexes with N-heterocyclic carbene (NHC) ligands that are not available in their free form, but it also serves as a potent precursor for NHC-stabilized silicon(IV) cations (see scheme). Selected examples are shown in which NHCSiCl4 reacts as a source of carbene or silicon cations, depending on the reaction conditions. NHC: 1,3-dimethylimidazolidin-2-ylidene.
- Rhodium(III)-Catalyzed Three-Component Reaction of Imines, Alkynes, and Aldehydes through CH Activation
Ji-Rong Huang, Qiang Song, Yu-Qin Zhu, Liu Qin, Prof. Dr. Zhi-Yong Qian and Prof. Dr. Lin Dong
Article first published online: 31 OCT 2014 | DOI: 10.1002/chem.201404576
Efficient approach: An efficient rhodium(III)-catalyzed tandem three-component reaction of imines, alkynes, and aldehydes through CH activation has been developed (see scheme). High stereo- and regioselectivity, as well as good yields were obtained in most cases. The simple and atom-economical approach offers a broad scope of substrates, providing polycyclic skeletons with potential biological properties.
- Chloride-Selective Electrodes Based on “Two-Wall” Aryl-Extended CalixPyrroles: Combining Hydrogen Bonds and Anion–π Interactions to Achieve Optimum Performance
Jad Sabek, Dr. Louis Adriaenssens, Tomàs Guinovart, Dr. Enrique J. Parra, Prof. F. Xavier Rius, Prof. Pablo Ballester and Dr. Pascal Blondeau

A marriage of hydrogen bonds and anion–π interactions leads to highly chloride-selective solid-contact electrodes based on “two-wall” aryl-extended calixpyrroles and multiwall carbon nanotubes. The interplay between binding strength and selectivity is the key for the receptor to reach optimum sensing performance (see figure).
- Kekulé versus Lewis: When Aromaticity Prevents Electron Pairing and Imposes Polyradical Character
Georges Trinquier and Jean-Paul Malrieu
Article first published online: 31 OCT 2014 | DOI: 10.1002/chem.201403952
Lewis bond-pairing violation: Despite accepting perfect bond pairing, some polycyclic conjugated molecules will prefer diradical or polyradical singlet ground states to maximize aromatic energy stabilization (see figure).
