Cover Picture: Multivalency in the Gas Phase: The Study of Dendritic Aggregates by Mass Spectrometry (Angew. Chem. Int. Ed. 27/2004)

43_27/2004The deconvoluted mass spectrum shown in the cover picture of a third-generation poly(propylene imine) dendrimer to which one to eight guest molecules are bound indicates that the complex with four guest molecules is the most abundant. Each of these aggregates can be selected, and the guests can be removed one by one by collision-induced dissociation (CID). The results provide new insight into the role of important secondary interactions in the gas phase. For more information, see the Communication by E. W. Meijer and co-workers on page 3557 ff.
