Flexible and dynamic channels created by an interdigitated framework of microporous coordination polymers are shown on the cover picture. The compound undergoes reversible crystal‐to‐crystal transformation from a nonporous (closed‐form) to a microporous (open‐form) structure, which is triggered by adsorption of supercritical gases. A hysteretic isotherm, shown bottom left, displays abrupt adsorption at a gate‐opening pressure and equally sharp desorption at a gate‐closing pressure. More about this coordination polymer is reported in the Communication by S. Kitagawa et al. on page 428 ff.
