Cover Picture: Expanding and Shrinking Porous Modulation Based on Pillared-Layer Coordination Polymers Showing Selective Guest Adsorption (Angew. Chem. Int. Ed. 25/2004)
To expand or shrink are properties of the new pillared-layer porous coordination polymers shown in the cover picture. These features show that coordination polymers are much softer than generally believed. The adsorption selectivity exhibited by these new zeolite-like materials arises from a simple change in the organic-pillar module, and may find applications in molecular separation techniques.
