Cover Picture: Bioinspired Superhydrophobic Coatings of Carbon Nanotubes and Linear π Systems Based on the “Bottom-up” Self-Assembly Approach (Angew. Chem. Int. Ed. 31/2008)
Superhydrophobic and self-cleaning coatings are created from the physical interaction between carbon nanotubes and oligo(p-phenylenevinylene)s. In their communication on page 5750 ff. A. Ajayaghosh et al. show that the nanocomposite with micrometer-sized hills and valleys as well as a nanoscale paraffin coating of hydrocarbon chains gives high contact angles and a very small slide angle, thus allowing water droplets to roll along the surface, generating the ability to self-clean, akin to a lotus leaf.

Some achiral compounds can rotate the plane of polarized light. B. Kahr, W. Kaminsky et al. describe in their Minireview on page 5706 ff. the conditions that must be fullfilled to achieve this phenomenon.

Planar Coordinated Iron
H. Kageyama et al. describe in their Communication on page 5740 ff. the topochemical reaction of Sr3Fe2O7 to ladder compound Sr3Fe2O5, which opens up new possibilities for the chemistry of square planar iron oxides and the physics of n-legged ladder systems.
