About this collection
Zeolitic Imidazolate Framework-8 (ZIF-8) is an archetypical Metal-Organic Framework that is often used to develop crystal engineering methods and explore new properties in porous materials. By developing new preparation protocols to control the ZIF structure (from amorphous to crystalline with specific phases), by imparting exogenous hierarchical porosity using templating agents, and by defining synthetic methods for the preparation of core-shell particles, ZIF-8 research will be able to further expand knowledge in porous materials and progress their practical applications. In a different research direction, the potential of ZIF-8 is currently under investigation by developing host-guest systems and composites; these include the integration of ZIFs with biomolecules, polymers, ceramics, and other porous materials. This selection of articles, handpicked by Advisory Board Member, Professor Paolo Falcaro, Graz University of Technology, would point to the most recent development in engineering ZIF-8-based materials.
