Short summary
Investigations of metal–organic frameworks are presented. This substance class is of interest for applications in gas storage (hydrogen, methane), separation, catalysis, and sensor technology. The properties of the material depend on the mobility of alkyl or alkyloxy side chains. We have determined that the side-chain methylene groups move highly anisotropically with a relatively short correlation time. Furthermore, we could improve the analysis procedure for the experiment used here.
