Cover Feature: Growth of ZIF‐8 MOF Films with Tunable Porosity by using Poly (1‐vinylimidazole) Brushes as 3D Primers (Chem. Eur. J. 54/2020)

Abstract

ZIF‐8 (based on Zn and 2‐methylimidazole) MOF film growth can be controlled by using SI‐ATRP‐synthesized polymeric brushes as 3D primers. This strategy relies on the inclusion of chemical moieties in the brush, which are compatible with MOF chemical structure. According to such criteria, Poly(1‐vinylimidazole) brushes with increasingly higher grafting densities were selected. Aside from the inherently hydrophobic microporosity arising from ZIF‐8 structure, our approach renders control over the proportion of constructional mesoporosity, which allow differential adsorption. More information can be found in the Full Paper by O. Azzaroni, M. Rafti, et al. on page 12388.

Synthesis, structural characterization, and carbon dioxide and hydrogen adsorption of a new three-dimensional metal organic framework Zn(BTC)4

“…Metal organic frameworks (MOFs) are a type of important hybrid inorganic-organic material, 1 and due to their unique topological structure, their applications have attracted more and more attention. 2 Most MOFs have high porosity and good stability, 3 controllable pore structures, and large specific surface areas. 4 Therefore, MOFs have extensive application prospects compared with other porous materials, for example, in chiral catalysis, 5 adsorption separation, 6 adsorption storage, 7 magnetic materials, 8 and optical materials.…”
