Diffusion-rate sieving of propylene and propane mixtures in a cooperatively dynamic porous crystal
2024
Overview
Selective molecular recognition is an important alternative to the energy-intensive industrial separation process. Porous coordination polymers (PCPs) offer designing platforms for gas separation because they possess precise controllability over structures at the molecular level. However, PCPs-based gas separations are dominantly achieved using strong adsorptive sites for thermodynamic recognition or pore-aperture control for size sieving, which suffer from insufficient selectivity or sluggish kinetics. Developing PCPs that work at high temperatures and feature both high uptake capacity and selectivity is urgently required but remains challenging. Herein, we report diffusion-rate sieving of propylene/propane (C

Porous coordination polymers (PCPs) are commonly used in gas separation processes but developing PCPs that work at high temperatures and feature both high uptake capacity and selectivity remains challenging. Here, the authors report diffusion-rate sieving of propylene/propane at 300 K by constructing a PCP whose global and local dynamics cooperatively govern the adsorption process via gate opening for propylene and diffusion regulation for propane.
