Cover Picture: Engineering Multifunctional Capsules through the Assembly of Metal–Phenolic Networks (Angew. Chem. Int. Ed. 22/2014)

Multifunctional capsules were assembled through interactions between metal ions and a single organic ligand. In their Communication on page 5546 ff., F. Caruso et al. show that a common phenolic plant compound, tannic acid, can be used to coordinate a variety of metals, yielding a library of metal–phenolic network (MPN) capsules. The functional properties of the MPN capsule are determined by the coordinated metals and can be tailored for various applications.

Chiral Boron Clusters The [B30]− cluster exists as a pair of planar structures with a hexagonal hole at different positions. J. Li, L.-S. Wang, and co-workers show in their Communication on page 5540 ff. that these two isomers are enantiomers.1 Targeted Synthesis In their Communication on page 5672 ff., D. C. Johnson and co-workers describe how designed precursors can be used to direct the self-assembly of targeted intergrowth structures.1 Protein Networks In their Communication on page 5680 ff., R. Tampé et al. describe a new way to arrange fusion proteins in a biocompatible hydrogel with minimal distortion using two-photon activation.1
