Reversible binding of CO2 …︁ can be realized with borane–phosphane frustrated Lewis pairs (FLPs). In their Communication on page 6643 ff., G. Erker et al. describe how the greenhouse gas CO2 is captured to form both cyclic and acyclic adducts through PC and OB bond formation. The reaction is reversed and CO2 released when the temperature of the solution is raised. Theoretical analysis describes CO2 binding by FLPs as a synchronous concerted reaction.

A chiral organocatalyst that is excited by UV light and is capable of transferring the excitation energy to a bound substrate is presented by T. Bach et al. in their Communication on page 6640 ff. The energy that is provided by sensitization allows a photocycloaddition in a chiral environment and thus the synthesis of the product is achieved with high enantiomeric excess.

Outside contact: Cells in multicellular organisms regulate their adhesion through specialized integrin receptors, which relay signals bidirectionally between the inside and outside of cells. The transmembrane domains (see picture, blue; the integrin–talin complex is red and green) of integrins are the center of the signaling process. Recently, structures of these domains have been reported that shed light on the signal transduction mechanism.

Zipper examined: Elegant unzipping procedures result in the clean opening of multiwalled carbon nanotubes, leading to graphene nanoribbons (see scheme). Since graphene exhibits outstanding electronic properties, this method may be important in the development of modern nanoelectronic applications.
