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).

    Glowing results: A strongly emissive copper iodide complex with a hybrid ligand exhibits strong yellow emission in the solid state (see picture). It can be electrospun with poly(methyl methacrylate) to give luminescent composite fibers.

  2. Strongly Coupled Pt[BOND]Ni0.3Co2.7O4 Hybrid Nanoflowers with Remarkably Enhanced Catalytic Performance

    Side-stepping stoichiometry: A low-cost facile synthetic method has been developed to fabricate strongly coupled Pt[BOND]Ni0.3Co2.7O4 porous hybrid nanoflowers. Interestingly, the whole synthesis is accomplished without any surface-modification techniques. The as-obtained “nonstoichiometric” hybrid nanocatalyst exhibits remarkable enhanced catalytic performance for the oxidation of CO (see picture).

  3. Synthesis, Structures, and Single-Molecule Magnet Behaviour of High-Nuclearity Nickel(II) Dicubane-Type Complexes with Pyridyl–Alcohol Ligands

    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 [Ni83-Cl)33-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.

  5. Effects of Chemical Composition, Film Thickness, and Morphology on the Electrochromic Properties of Donor–Acceptor Conjugated Copolymers Based on Diketopyrrolopyrrole

    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.
