      The cover picture shows the release of the luminescent rhenium coordination complex (yellow spheres) in solution. This release is triggered by electrochemical stimulus applied through the cable to the metallopolymer, which is represented by the splash of blue paint. The irreversibility of the electrochemical release is highlighted by holes in the graph paper. G. Valenti, F. Paolucci, R. J. Forster, and co-workers outline the photophysical and electrochemical properties of a novel metallopolymer containing [Re(bpy)(CO)3]+ moieties coordinated to a poly(4-vinylpyridine) polymer chain in their Full Paper on page 55 ff. Release of the metal complexes can be triggered by oxidation or reduction of the rhenium complex.

      Frontispiece

      Article first published online: 22 JAN 2013 | DOI: 10.1002/cplu.201380171

      Thumbnail image of graphical abstract

      The frontispiece shows metal-mediated base pairing, where the hydrogen bonds present in natural base pairs are formally replaced by coordinative bonds to metal ions located along the helical axis. These base pairs can be made by introducing artificial ligand-based nucleosides into the nucleic acid sequence. In the presence of suitable transition-metal ions, these metal ions will site-specifically bind to the nucleic acid. As a result, DNA can be used as a supramolecular scaffold for metal-based functionality, adding new physical properties to this biomacromolecule. The latest developments in this field are highlighted in the Review by Philipp Scharf and Jens Müller on page 20 ff.

      Biotransformation of odorants and volatiles in humans is essential for understanding their potential roles with regard to physiological action. Eucalyptol, a common odorant, is shown to yield a range of chiral metabolites that are detectable in human urine, thereby revealing information on rarely investigated pathways in human metabolism (see figure).

    5. Designed Synthesis of Functionalized Two-Dimensional Metal–Organic Frameworks with Preferential CO2 Capture (pages 86–91)

      Qiuju Yan, Yichao Lin, Dr. Pengyan Wu, Li Zhao, Lujie Cao, Prof. Luming Peng, Assoc. Prof. Chunlong Kong and Prof. Liang Chen

      Article first published online: 21 NOV 2012 | DOI: 10.1002/cplu.201200270

      Thumbnail image of graphical abstract

      What a catch! A series of three functionalized metal–organic frameworks have been fabricated by the combination of direct synthesis (template-free) and covalent modification. The resulting frameworks display fairly good thermal stability and moisture resistance. Regardless of the moderate surface area, the grafted carbonyl functionalities enhance the selective CO2 adsorption capacity (see figure).

    6. Sol–Gel-Derived, Calcium-Based, Copper-Functionalised CO2 Sorbents for an Integrated Chemical Looping Combustion–Calcium Looping CO2 Capture Process (pages 92–100)

      Dr. Agnieszka M. Kierzkowska and Prof. Christoph R. Müller
