pH-controlled inclusion and release of oxyanions by denrimers bearing methyl orange moieties
Stephan, H.; Spies, H.; Johannsen, B.; Kaufmann, C.; Vögtle, F.;
We report the synthesis of POPAM-dendrimers, bearing up to 64 chromophores at their periphery. For these dendrimers radiotracer technique was used to study the liquid-liquid partition of pertechnetate and 14C-labeled nucleotides in trichloromethane-aqueous systems. Inclusion and release of guest molecules can be controlled by changing the pH. The extraction efficacy increases with rising generation number.
