Cover Figure


COVER Photomicrograph of an organic inclusion compound (crossed polarizers, l plate) showing changes in interference colors for differently oriented domains. These domains, which are organized by host-guest hydrogen bonding, can be interconverted with external force, and their ferroelastic response can be modified with impurities. Such systems are featured in the special section on supramolecular chemistry and self-assembly in this issue. 2395 [Image: M. D. Hollingsworth and M. E. Brown]
