Lipophilic urea-functionalized dendrimers as efficient carriers for oxyanions

Stephan, H.; Spies, H.; Johannsen, B.; Klein, L.; Vögtle, F.

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 quantitavely by tracer methods. Their pH dependancy allows to steer the release of guest molecules from the dendrimer host.
