Cover Picture: Isostructural Coordination Capsules for a Series of 10 Different d5–d10 Transition-Metal Ions (Angew. Chem. Int. Ed. 39/2006)
An isolated space for size- or shape-selective dynamic molecular recognition and metal-triggered chemical reactions is offered by the cavity within nanocapsules. In their Communication on page 6488 ff., M. Shionoya and co-workers describe a series of isostructural octahedral capsules prepared from a common tridentate ligand and ten different transition-metal ions, as highlighted in green in the cover picture, and demonstrate site-specific exchange of the anions coordinated within the cavity to the metal centers.
Also of Interest
Conjugated polymers that contain cyclophane units in the main chain are promising materials as molecular wires. In their Minireview on page 6430 ff., Y. Morisaki and Y. Chujo give an overview of recent developments in this class of polymer.
A Natural Cancer Suppressor
Many cells have a control system based on the tumor-suppressor protein p53 to prevent cancer development. In their Review on page 6440 ff., H. Kessler, J. Buchner, et al. describe the structure and regulation of p53 as well as new therapy possibilities.
In their Communication on page 6462 ff., M. Y. Gao and H. Niu report the synthesis of cadmium thiolate nanowires, whose diameters can be tuned by using poly(acrylic acid), and their use as sacrificial templates for the preparation of long CdTe nanotubes.
