Coordination Chemistry in Zeolites

Journal of inclusion phenomena and molecular recognition in chemistry, 1995
Zeolites are relatively rigid inorganic matrices with cavities and channels of molecular dimensions and of different sizes and shapes. Transition metal ion (TMI) complexes in molecular sieves have three main characteristics: (1) the complexes have strongly reduced mobility with respect to their solution mobility and deactivating aggregations may be ...

Taming Flexibility: Synergistic Pore and Polarity Engineering in a MOF for High‐Efficiency Xe/Kr Separation

Advanced Science, EarlyView.
Through a mixed‐ligand strategy that precisely regulates pore size and framework polarity, the Xe adsorption behavior is transformed from flexible to near‐rigid. ZIF‐7‐Cl(20) achieves sensitive recognition, efficient capture, and high selectivity for Xe, enabling high‐efficiency separation from Xe/Kr mixtures.
