ChemPlusChem 6/2015: Highly Important Paper

Articles that reviewers rate in the top 20% in terms of importance deserve special attention. We are pleased to highlight a paper of this caliber in Issue 6: Mohammad Gholinejad et al. describe a novel heterogeneous catalystconsisting of CuFe2O3 and Pd0 nanoparticles assembled on silica microparticles (see picture). This catalyst effects the Sonogashira coupling reaction of aryl iodides and bromides with various alkynes, a reaction that typically requires both palladium and copper cocatalysts, neither of which are readily recovered. The added extra of the new catalyst is that it can be recovered easily with a magnet, then rinsed, dried, and reused.

The cover of this issue is graced by triazatruxenes, melanin-inspired compounds with promising optoelectronic properties, devised by Paola Manini et al. (cover profile).

  1. Preparation and Photoelectric and Magnetic Properties of Cu2MnSnS4 Nanosheets

    Prof. Liang Shi, Yanan Li, Chunyan Wu and Prof. Ren-Kui Zheng

    Article first published online: 29 JUN 2015 | DOI: 10.1002/cplu.201500163

    Cu2MnSnS4 nanosheets oriented parallel to the (002) crystal plane have been synthesized through a simple solution method. The Cu2MnSnS4 nanosheets show enhanced conductivity under light irradiation, disclosing their suitability for photovoltaic applications (see figure). Weakly ferromagnetic behavior at low temperatures was found for the Cu2MnSnS4 nanosheets.

  2. Utilizing Benign Oxidants for Selective Aerobic Oxidations Using Heterogenized Platinum Nanoparticle Catalysts

    Christopher S. Hinde, Arran M. Gill, Dr. Peter P. Wells, Prof. T. S. Andy Hor and Dr. Robert Raja

    Article first published online: 29 JUN 2015 | DOI: 10.1002/cplu.201500195

    Tuned cats.: Well-defined platinum nanoparticles are generated in situ by anion extrusion within porous framework architectures (see figure). In these catalysts the local structural environment of the active site is controlled by the calcination conditions, and thus industrially significant, sustainable catalytic oxidation reactions are possible with tert-butyl hydroperoxide (TBHP) or oxygen.

  3. Dithienothiophene-Based Triphenylamine-Containing Branched Copolymers for Electrochromic Applications

    Ching Mui Cho, Wei Teng Neo, Dr. Qun Ye, Prof. Xuehong Lu and Dr. Jianwei Xu

    Article first published online: 24 JUN 2015 | DOI: 10.1002/cplu.201500192

    Broad-spectrum results: A series of electrochromic dithienothiophene-based branched copolymers with triphenylamine as a co-monomer are described. Reversible multicolored optical changes are observed and depend on the triphenylamine content (see figure). The effect of triphenylamine on the electrochromic properties is also described.

    In a bind: Fragment-based screening has identified 14 fragments that bind to Escherichia coli gyrase B. A fragment growing on a low-affinity fragment (KD=233 μM, IC50=628 μM) has led to the development of a new class of potent phenyl aminopyrazoles inhibitors against E. coli gyrase B (IC50=160 nM).

  5. A Facile and One-Step Synthesis of Visible-Light-Responsive Silver and Mesoporous Carbon Comodified Carbon–Zinc Oxide Composites

    Dr. Fangxiao Wang, Dr. Lin Liang, Dr. Lei Shi, Dr. Mengshuai Liu and Prof. Dr. Jianmin Sun

    Article first published online: 23 JUN 2015 | DOI: 10.1002/cplu.201500158

    Light harvesting: Visible-light-responsive Ag and mesoporous carbon (mC) comodified C[BOND]ZnO composites with excellent photocatalytic activity have been fabricated by using a green, economical process in CO2-expanded ethanol without additional precipitant or mesoscale templates. The remarkable improvement in activity is attributed to synergistic effects between modified Ag and mC, doped C, and small-sized ZnO (see figure).
