摘要

Rotaxane dendrimers are a recent and novel family of mechanically interlocked dendrimers.Merging the unique characteristics of both rotaxanes and dendrimers endows the resultant rotaxane dendrimers with appealing topologic structures as well as promising properties.Thus,the design and construction of novel rotaxane dendrimers has attracted considerable attention during the past two decades [1].However,only a very few successful examples of discrete,well-defined rotaxane dendrimers equipped with mechanically interlocked moieties on branches have been realized.Because in-depth investigations of the potential applications of rotaxane dendrimers requires the facile and efficient preparation of rotaxane dendrimers with complex and diverse structures,the development of a highly efficient synthetic strategy for producing high-generation rotaxane branched dendrimers is extremely desirable.
