Cover Picture: Reversible Redox Reactions in an Extended Polyoxometalate Framework Solid (Angew. Chem. Int. Ed. 36/2008)
Like a revolving door that can easily open, close, and return to the start, the first framework material that can undergo reversible electron-transfer reactions is described by L. Cronin et al. in their Communication on page 6881 ff. The solid contains large pockets in which the redox reagents can reside; the manganese(II)/(III)-containing framework is able to move between these oxidation states and is the first in a new class of redox solids.

P. P. Edwards, J. R. P. Williams et al. present in their essay on page 6758 ff a unifying approach to the description of electron transfer processes in various biological and artificial materials.
Microporous metal–organic frameworks (MOFs) are promising materials for H2 storage. J. R. Long and M. Dincă report in their Review on page 6766 ff. that the incorporation of coordinatively unsaturated metal centers in MOFs increases the enthalpy of H2 adsorption.
A. Marx et al. describe in their Communication on page 6782 ff. the multiple site-specific introduction of spin labels in DNA which can be tolerated by DNA polymerases of eukaryotic, prokaryotic, and archaic origin.
