Cover Picture: Polymerization Catalyst Laser-Interference Patterning (Angew. Chem. Int. Ed. 41/2011)
Spatial patterning of a polymerization catalyst can be achieved rapidly and efficiently by means of laser interference. In their Communication on page 9665 ff., S. Mecking et al. describe how monomers, upon polymerization, give a replica of the patterned catalyst. The approach is illustrated by the generation of “wires” of polyacetylene, a prototype of a polymer that is not amenable to any postpolymerization processing.

The anion–π interaction has recently been recognized as a hitherto unexplored noncovalent bond, which has been investigated both experimentally and theoretically. The current state of research is analyzed by A. Frontera et al. in their Review on page 9564 ff.
In their Communication on page 9584 ff. D. M. Bassani and co-workers describe how optical information is written onto microscopic single crystals of a fullerene-based material by spatially controlling the rotation of its polarized emission.
In their Communication on page 9615 ff. N. R. Shiju, G. Rothenberg, et al. describe novel bifunctional solid catalysts that combine both acid and base functions. These new materials were used to catalyze one-pot tandem reactions.
