The preparations of Cu (Ⅱ) -dendrimer and the structure of Cu (Ⅱ) complexes and catalysis properties were reviewed. The Cu (Ⅱ) -dendrimer complexes involves the internal amidoamine groups and the carboxylic groups or amidoamine groups at the dendrimer surface. Simultaneously

the preparations of Cu (0) -dendrimer and catalysis properties are reviewed. The research demonstrated that there is a systematic decrease in the size of the generated Cu namoparticle with increasing dendrimer generation

and decreased greatly namoparticle aggregation. Some views on the future development of Cu-dendrimer are submitted.
