Assessing the adsorption selectivity of linker functionalized, moisture-stable metal–organic framework thin films by means of an environment-controlled quartz crystal microbalance

Abstract

The stepwise thin film deposition of the robust, hydrophobic [Zn₄O(dmcapz)₃]_n (dmcapz = 3,5-dimethyl-4-carboxy-pyrazolato) is reported. The adsorption of small organic probe molecules, including alkanols, toluene, aniline and xylenes, was monitored by an environment-controlled quartz crystal microbalance setup. The adsorption selectivity was tuned by introducing alkyl side chains in the dmcapz linker.
