By modifying amine groups in a metal-organic framework (MOF), Zhenqiang Wang and Seth M. Cohen of the University of California, San Diego, have shown that it’s possible to activate the “breathing” behavior of pores in the materials to selectively adsorb gases or other molecules. The finding marks the first time researchers have used a postsynthetic modification to trigger and control the flexibility of MOFs (J. Am. Chem. Soc., . . .
