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 nuclearity option: The condensation between two chemically different tetranuclear cubane-like clusters [Ni(μ3-Cl)(Cl)(HL)]4 (1; HL=2-methyl-1-(pyridin-2-yl)propan-2-ol) and [Ni(μ3-OH)(Cl)(HL)]4 (2) offers new access to higher nuclearity complexes, such as [Ni8(μ3-Cl)3(μ3-OH)5(μ-Cl)2Cl6(HL)7] (3; see figure), which displays single-molecule magnet behaviour.

Super stars: (4-Formylphenylethynyl)ruthenium complexes (see figure) are shown to undergo “chemistry-on-complex” Horner–Wadsworth–Emmons coupling to afford a range of tri- and tetraruthenium-functionalized star molecules and a nonaruthenium dendrimer. The products are nonlinear optical (NLO)-active, with linear optical properties that are redox-switchable.
- Effects of Chemical Composition, Film Thickness, and Morphology on the Electrochromic Properties of Donor–Acceptor Conjugated Copolymers Based on Diketopyrrolopyrrole
Wei Teng Neo, Dr. Zugui Shi, Ching Mui Cho, Prof. Soo-Jin Chua and Dr. Jianwei Xu
Article first published online: 3 JUL 2015 | DOI: 10.1002/cplu.201500182
On and off: A series of electrochromic diketopyrrolopyrrole-based conjugated polymers are synthesized and characterized. Reversible colored-to-transmissive optical changes with high contrasts and ambient redox stabilities are observed (see figure). The influences of donor-to-acceptor ratio and film morphology on the electrochromic performance are addressed.

Article first published online: 1 JUL 2015 | DOI: 10.1002/cplu.201500206
Got it covered! The synthesis of palladium bis(dithiolene) coordination nanosheets (CONASH) has been achieved by both liquid–liquid and gas–liquid interfacial reactions between a metal salt in the aqueous phase and a ligand dissolved in the organic phase (see figure).

Focus on anodes: The application of microbial fuel cells for wastewater treatment has emerged as a green energy technology. In recent work leading to microbial fuel cells with enhanced performance, the anode has been manipulated to improved its biocompatibility, provide sufficient space for bacteria, and facilitate electron transfer.
