Abstract

Urea-functionalized dendrimers are prepared which show very efficient phase transfer, in particular of the diagnostically relevant anions pertechnetate, perrhenate and ATP; the extractability rates are evaluated quantitatively by tracer methods; their pH dependancy allows controlled release of guest molecules from the dendrimer host.
