包裹铑纳米团簇的第4代苯基甲基树状大分子（TPP-DPA G4）和聚胺胺树状大分子（PAMAM G4- oh）对烯烃和硝基芳烃的加氢非常有效，可提供高的TOF（高达17,520 h(-1)）；纳米笼催化剂的重要特点是，底物可以穿过纳米簇保护基团的分支，而不会从树状聚合物中释放纳米簇。
The phenylazomethine dendrimer generation 4 (TPP-DPA G4) and polyamidoamine dendrimer (PAMAM G4-OH) encapsulating rhodium nanocluster were found to be highly effective for olefin and nitroarene hydrogenations, affording high TOF (up to 17,520 h(-1)); the important feature of the nanocage catalyst is that substrates can pass through the branches of the protecting groups of nanoclusters without releasing nanoclusters from the dendrimer.
