45_27/2006Cover Picture: Formation of Self-Organized Dynamic Structure Patterns of Barium Carbonate Crystals in Polymer-Controlled Crystallization (Angew. Chem. Int. Ed. 27/2006)

The Belousov–Zhabotinsky reaction with its typical concentric ring pattern is described for a precipitation for the first time by T. Wang, A.-W. Xu, and H. Cölfen in their Communication on page 4451 ff. The formation and self-organization of BaCO3 nanoparticles can be directed with a new phosphonated block copolymer: short to ultralong nanofibers and, ultimately, ring patterns are obtained. This system could help to explain natural pattern formation. The cover picture shows observed and simulated Belousov–Zhabotinsky ring patterns, as well as the molecular structure of the block copolymer.
