An organic molecular crystal that demonstrates “on–off” porosity switching is presented by A. Cooper and co‐workers in their Communication on page 749 ff. This organic solid, which is composed of intrinsically porous cage molecules, can reversibly interconvert between porous and nonporous polymorphs in response to solvent vapor. The switch is facilitated by both translational and conformational mobility in the molecular crystal.
