1Introduction The chemistry of dendrimers is a fast developing field and has brought about a tsunami of research activity since Vogtle reported the first preparation in 1978. These hyperbranched macromolecules have grown out of chemists' imagination and have challenged synthetic chemists with their architectural complexity and intriguity. The potentials of these macromolecules are extensive and are synthesized using both organic and inorganic cores from which different scaffoldings are built, and upon which functionalities are attached for specific applications. The synthesis and characterizations of cisplatin and rhenium(Ⅰ) containing PAMAM derivatives will be discussed.
