-alkane impurities). In effect, temperature-dependent structural flexibility enables modulation of guest diffusion kinetics and adsorption thermodynamics. CALF-20 thereby achieves propylene purification from propane and butadiene purification with exceptional selectivity. Structural and computational insights into the mechanisms governing the selective separation of light hydrocarbons using CALF-20 reveal the potential of targeted flexible nanoporous materials with dynamically tunable pore environments, paving the way for next-generation separation technologies in the petrochemical and energy sectors.
