ChemPlusChem 7/2015: Methods, Mechanisms, and Materials
Among the intriguing articles this month is a Review by Nadav Amdursky on electron transfer across α-helical peptides, which are promising biomolecules for integration into bioelectronic devices. The synthesis of graphitic carbon nitride through the thermal condensation of guanidine salts is reported in a Full Paper by Shiguo Zhang. Ali Coskun (also featured in our Early Career Series) describes novel porous graphene networks that are prepared by the catalyst-free condensation reaction between functionalized graphene sheets and organic linkers.

- A Triazolyl-Pyridine-Supported CuI Dimer: Tunable Luminescence and Fabrication of Composite Fibers
Dr. Shi-Qiang Bai, Dr. Dan Kai, Dr. Karen Lin Ke, Dr. Ming Lin, Dr. Lu Jiang, Dr. Ying Jiang, Prof. David James Young, Dr. Xian Jun Loh, Dr. Xu Li and Prof. T. S. Andy Hor

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.
- Strongly Coupled PtNi0.3Co2.7O4 Hybrid Nanoflowers with Remarkably Enhanced Catalytic Performance

Side-stepping stoichiometry: A low-cost facile synthetic method has been developed to fabricate strongly coupled PtNi0.3Co2.7O4 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).
- Synthesis, Structures, and Single-Molecule Magnet Behaviour of High-Nuclearity Nickel(II) Dicubane-Type Complexes with Pyridyl–Alcohol Ligands
Sophie Hameury, Laure Kayser, Dr. Roberto Pattacini, Dr. Patrick Rosa, Dr. Anne-Laure Barra and Dr. Pierre Braunstein
Article first published online: 3 JUL 2015 | DOI: 10.1002/cplu.201500184
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.
