Graphical Abstract
Walking on the edge: Mass spectrometry aided by H/D exchange experiments provides evidence for a surprisingly quick movement of [18]crown-6 units across the periphery of POMAM dendrimers (see picture). In the diluted gas phase, dissociation/reassociation equilibria do not play any role. The movement of the crown ether units resembles that of astronauts on the outside of a space station.
