| Popis: | We report the synthesis of POPAM dendrimers, bearing up to 64 chromophores at their periphery. For these dendrimers, a radiotracer technique was used to study the liquid-liquid partition of pertechnetate and (14)C-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. |
