On p. 3275 ff. C. A. Fernandez, P. K. Thallapally et al. present a study on the carbon‐dioxide‐induced expansion and contraction of the porous lattice in a partially fluorinated metalorganic framework as a function of temperature. The results indicate that two structural transitions take place during CO 2 adsorption. The first one (at low CO 2 pressures) corresponds to shrinkage of the framework while, at relatively high CO 2 pressures, a framework expansion takes place, as evidenced by a large hysteresis loop in the adsorption/desorption isotherms and an associated energy cost.
