New Multichromophoric Ligand for Light Harvesting
Light-harvesting antennae are of great importance for the development of efficient solar cells. Multichromophoric systems capable of harvesting light are of interest as they can be used in multicomponent systems in which the different chromophores are in close contact to favor energy and/or electron transfer, so that the excitation energy can be funneled to a specific acceptor. If one of these chromophores is also a good ligand for metal ions, new interesting properties can arise in a supramolecular system, such as control of the energy/electron transfer processes by changing the metal ion or the ability to generate supramolecular architectures and coordination polymers. To find out more about this subject read the paper by Marc Gingras, Aix-Marseille Université, France, Giacomo Bergamini, University of Bologna, Italy, and co-workers.

An unexplored class of chiral thiohydantoins can be used as efficient catalysts for iodoaminations while additives effect the regiochemistry. Also quaternary stereocenters can be easily generated with this metal-free, organocatalytic protocol.
- Earth-Abundant Oxygen Evolution Catalysts Coupled onto ZnO Nanowire Arrays for Efficient Photoelectrochemical Water Cleavage
Chaoran Jiang, Dr. Savio J. A. Moniz, Dr. Majeda Khraisheh and Dr. Junwang Tang
Article first published online: 22 AUG 2014 | DOI: 10.1002/chem.201403067
Efficient water splitting: High performance of 1D ZnO nanowire arrays was achieved through optimization of their length and diameter followed by surface modification with earth-abundant nickel borate (Ni-B) and cobalt phosphate (Co-Pi) oxygen-evolution catalysts. Significantly, Ni-B/ZnO exhibits the lowest onset potential (0.3 V) and highest photocurrent of 1.2 mA cm−2 at 0.9 V vs. RHE (see figure). Furthermore, the stability of ZnO was remarkably enhanced by coating with Ni-B as a protection layer on ZnO.
- Aza-Crown Ether Complex Cation Ionic Liquids: Preparation and Applications in Organic Reactions
Dr. Yingying Song, Chen Cheng and Prof. Huanwang Jing
Article first published online: 22 AUG 2014 | DOI: 10.1002/chem.201403118
Jewel in the crown: Nine new and room-temperature aza-crown ether complex ionic liquids (aCECILs) composed of multiple cations and anions were fabricated through a convenient procedure (see scheme). Some of them were used as catalysts in various organic reactions, such as the cycloaddition reaction of CO2 to propylene oxide, esterification of acetic acid and alcohols, the condensation of aniline and propylene carbonate, and Friedel–Crafts alkylation of indole with aldehydes.
- Stereoselective CH Borylations of Cyclopropanes and Cyclobutanes with Silica-Supported Monophosphane–Ir Catalysts
Ryo Murakami, Kiyoshi Tsunoda, Dr. Tomohiro Iwai and Prof. Dr. Masaya Sawamura
Article first published online: 22 AUG 2014 | DOI: 10.1002/chem.201404362
Heteroatom-directed CH borylations of small-ring carbocycles, such as cyclopropanes and cyclobutanes, were achieved with silica-supported monophosphane–Ir catalysts (see scheme). Borylation occurred at the CH bonds located γ to the directing N or O atoms with exceptional cis stereoselectivity relative to the directing groups.
- Enzymatic Desymmetrising Redox Reactions for the Asymmetric Synthesis of Biaryl Atropisomers

Article first published online: 22 AUG 2014 | DOI: 10.1002/chem.201404509
Atropisomerism: Either enantiomer of atropisomeric biaryl hydroxyaldehydes may be synthesised in enantiomerically enriched form by desymmetrising atropselective enzymatic oxidation (with a galactose oxidase mutant) or reduction (with a ketoreductase; see scheme).
