Abstract Metal-organic frameworks (MOFs) are a class of porous materials with unprecedented chemical and structural tunability. Their synthetic versatility, long-range order, rich host–guest chemistry make MOFs ideal platforms for identifying design features advanced functional materials. This review addresses approaches to control MOF attributes realizing material properties such as charge conductivity, stability, surface area, flexibility. Along an updated account on employed in batteries...
Zirconium metal–organic frameworks (Zr-MOFs) are renowned for their extraordinary stability and versatile chemical tunability. Several Zr-MOFs demonstrate a tolerance missing linker defects, which create "open sites" that can be used to bind guest molecules on the node cluster.

Aminopolymer sorbents are leading candidates for extracting CO2 directly from the atmosphere under ambient conditions. For effective carbon capture, this requires not only that actively binds with amine groups of polymer low gas concentrations but also it readily diffuses through sorbent media to access as many binding sites possible. Unfortunately, high reactivity and diffusivity tend be mutually exclusive properties when comes small molecule transport within a polymer, posing significant...
