Increased crystal porosity and enhanced gas adsorption by intracolumnar gliding for broadband gas detection

A new three-level structural approach based on anion-induced intracolumnar gliding of stacked coordinatively unsaturated units is described for design of metal-organic crystals which exhibit concentration- and gas-specific adsorption of a variety of small molecules and could be employed for multiple and rapid qualitative and quantitative broadband detection of gases or gaseous mixtures.
