Cover Picture: Multiplexing Sensory Molecules Map Protons Near Micellar Membranes (Angew. Chem. Int. Ed. 25/2008)
Like mapping other worlds In their Communication on page 4667 ff., A. P. de Silva et al. describe proton concentration maps of detergent micelles obtained by the fluorescent multiplexing sensors (space-filling model). These sensors can change their positions and report information comprised of pKa values and emission wavelengths. These sensors serve as nanosized robot vehicles, as they send detailed data from humanly inaccessible environments.

Organocatalysts today belong to the normal repertoire of organic synthesis. A. Dondoni and A. Massi discuss in their Review on page 4638 ff. selected studies that address special issues, particularly stereochemical problems.
In their Communication on page 4662 ff., M. Lee et al. describe how dumbbell-shaped rod amphiphiles form hollow spheres with gated nanopores. The spheres are able to encapsulate and release cargos in a controlled manner.
S. L. Buchwald and K. L. Billingsley present in the Communication on page 4695 ff. a general system for the Suzuki–Miyaura cross-coupling of aryl halogenides with 2-pyridyl nucleophiles. The ideal catalyst was found to be [Pd2(dba)3] in combination with phosphine oxide ligands.
