5 April, 2017 - 00:00

 Boosting Catalytic Efficiency through Spatial Modulation

Spatial edition: A novel spatial-modulation approach has been developed to fabricate a Pd-metalated nanoporous polymer, which acts as an efficient and ligand-free heterogeneous catalyst for the cyanation of aryl halides. The catalyst displays high activity in the synthesis of benzonitriles, with high product yields, excellent stability and recycling, and broad functional-group tolerance.

Composite Electrolyte for All-Solid-State Lithium Batteries: Low-Temperature Fabrication and Conductivity Enhancement

5 April, 2017 - 00:00

 Low‐Temperature Fabrication and Conductivity Enhancement

Superionic conductivity: LATP–Bi2O3 composite solid electrolyte (LATP=Li1+xAlxTi2−x(PO4)3) shows very high total conductivity (9.4×10−4 S cm−1) at room temperature. The Bi2O3 acts as a microstructural modifier to effectively reduce the fabrication temperature and promote the densification of the LATP electrolyte, thereby improving its structural integrity and ionic conductivity.

Controlling the Hydrolysis and Loss of Nitrogen Fertilizer (Urea) by using a Nanocomposite Favors Plant Growth

5 April, 2017 - 00:00

Controlling the Hydrolysis and Loss of Nitrogen Fertilizer (Urea) by using a Nanocomposite Favors Plant Growth

Let it grow: A network-structured nanocomposite is fabricated and used as an excellent fertilizer synergist (FS), which could effectively inhibit the hydrolysis, reduce the loss, and enhance the utilization efficiency of nitrogen and thus decrease nonpoint agricultural pollution. The FS, which has high biosafety, exerted positive effects on the expression of nitrogen-uptake-related genes, ion flux in maize roots, crop growth, microbial communities, and organic matter in soil.

5 April, 2017 - 00:00

 Enhanced Photophysical Properties of Binuclear Blue Emitters

The Back Cover picture shows bimetallic platinum complexes, created by the combination of two specifically designed ligands, that show outstanding photophysical properties. The distance between the Pt atoms controls the color and the decay time, leading to a sky blue phosphorescent emitter with enhanced performance. More information can be found in the Communication by T. Strassner et al. (DOI:10.1002/cptc.201600065).

Functionalization of Ruthenium(II)(&#x3B7;6‐p‐cymene)(3‐hydroxy‐2‐pyridone) Complexes with (Thio)Morpholine: Synthesis and Bioanalytical Studies

Designer drugs: The {RuII(&#x3B7;6-p-cymene)} complexes of 3-hydroxy-2-pyridinone-functionalized with morpholine and thiomorpholine display low cytotoxic activity (see figure). This is associated with ligand-exchange reactions that result in cleavage of the pyridinone moiety from the ruthenium center.

Unveiling One-Dimensional Supramolecular Structures Formed through π–π Stacking of Phenothiazines by Differential Pulse Voltammetry

5 April, 2017 - 00:00

Unveiling One‐Dimensional Supramolecular Structures Formed through &#x3C0;–&#x3C0; Stacking of Phenothiazines by Differential Pulse Voltammetry

&#x3C0;–&#x3C0; Stacked 1D aggregates are evidenced in the study of the aggregation process of phenothiazines using differential pulse voltammetry (DPV) at micromolar concentrations. From the frictional resistance of the species in solution, determined by DPV, it is possible to verify the growth of 1D aggregates that may collapse to structures with lower anisometry at higher concentrated solutions.

Synthesis and Opioid Activity of Tyr1‐&#x3C8;[(Z)CF=CH]‐Gly2 and Tyr1‐&#x3C8;[(S)/(R)‐CF3CH‐NH]‐Gly2 Leu‐enkephalin Fluorinated Peptidomimetics

F atoms for PK insight: New fluoroalkene and trifluoroethylamine analogues of the endogenous opioid neuropeptide Leu-enkephalin were synthesized, and the functional activity of these new peptides was evaluated. The fluoroalkene peptidomimetic exhibited low nanomolar functional activity (5±2 nm and 60±15 nm for &#x3B4;- and &#x3BC;-opioid receptors, respectively) with a &#x3BC;/&#x3B4;-selectivity ratio that mimics that of the natural peptide.

Synthesis and Antiproliferative Effect of Ethyl 4‐[4‐(4‐Substituted Piperidin‐1‐yl)]benzylpyrrolo[1,2‐a]quinoxalinecarboxylate Derivatives on Human Leukemia Cells

An antileukemia army: New ethyl 4-[4-(4-substituted piperidin-1-yl)]benzylpyrrolo[1,2-a]quinoxalinecarboxylate derivatives were designed, synthesized, and evaluated against five leukemia cell lines, as well as normal human peripheral blood mononuclear cells. These new pyrrolo[1,2-a]quinoxalines showed interesting cytotoxic potential against all leukemia cell lines tested, with three pyrroloquinoxalines having particularly high activity against leukemia and low activity against normal hematopoietic cells.

Cancer-Specific, Intracellular, Reductive Activation of Anticancer Pt<sup>IV</sup> Prodrugs

5 April, 2017 - 00:00

Cancer‐Specific, Intracellular, Reductive Activation of Anticancer PtIV Prodrugs

Reductive activation under oxidative conditions: A prodrug consisting of one PtIV center and two protected aminoferrocene-based pro-reductants was prepared. It was uptaken by cells, activated in the cancer-specific microenvironment (high H2O2) with reduction of PtIV via two intramolecular one-electron transfers. The drug formed in this way induced cell death both in cisplatin-sensitive and resistant cell lines (see scheme).

5 April, 2017 - 00:00

 Their Magnetic and Optical Properties

The rational design of well-defined core–shell gold Prussian-blue analogous nanoparticles is presented together with an in-depth study of their optical and magnetic properties. It is shown that both properties may be tuned by modifying various parameters. This approach constitutes a first step towards the design of Prussian-blue analogous magnetoplasmonic heterostructures. The cover artwork was designed by Mr. S. Bertrand. More information can be found in the Full Paper by J. Long and J. Larionova et al. (DOI: 10.1002/chem.201605903).
