The release and uptake of solvent molecules takes place through a reversible single crystal-to-single crystal transformation. Importantly, the temperature of dehydration can be increased by <i>ca</i> 40 °C through the decoration of the channels by introduction of OH groups on the backbone of the organic tecton.
