50_35/2011Cover Picture: Transition-Metal-Catalyzed Unzipping of Single-Walled Carbon Nanotubes into Narrow Graphene Nanoribbons at Low Temperature (Angew. Chem. Int. Ed. 35/2011)

Narrow, smooth-edged graphene nanoribbons are needed for graphene electronics to replace the current silicon technology. In their Communication on page 8041 ff., J. Wang, F. Ding, et al. report a smart strategy for cutting single-walled carbon nanotubes (gray) into narrow graphene nanoribbons in H2 gas (green) with a single transition-metal atom (Cu, red) as the chemical scissors.

Shuttle-Mediated Deliveryfor001

The treatment of brain disorders is still a great challenge because of the blood–brain barrier (BBB). E. Giralt et al. show in their Review on page 7998 ff. how a vector-mediated approach, whereby the drug is coupled to a shuttle molecule that has the ability to cross the BBB, offers a potential solution.

Extended π Systemsfor002

Y. Matano et al. present in their Communication on page 8016 ff. the synthesis and characterization of a new class of arene-annulated phosphole–π systems, namely the diacenaphtho[1,2-b:1',2'-d]phospholes, often with a marked electron-transport capability.

Chemical Transformationsfor003

C. Crudden et al. describe a dinitrogen–rhodium complex with an N-heterocyclic carbene in their Communication on page 8100 ff. that undergoes two back-to-back single-crystal-to-single-crystal transformations to O2 and CO complexes.
