摘　　要：Interaction between heterogeneous,nanometer-sized building blocks(NSBBs)is fascinating from viewpoints of both structures and functions.We report the co-assembly of fullerene C_(60) and a chiral silver nanocluster(Ag_(6)),which yields C_(60) nanoarchitecture decorated with a small amount of Ag_(6).While Ag_(6) exhibits circular dichroism(CD)signal mainly in the ultraviolet(UV)region,the signal of the C_(60)-Ag_(6) hybrid extends to visible region(over 700 nm).Up to five pairs of CD signals were distinguished,which match well with the absorption of the C_(60) crystal.The successful chirality transfer from the guest of Ag_(6) to C_(60)-dominated supramolecular system indicates that the“sergeants and soldiers”effect is valid in architectonics of NSBBs.In addition,the doping of Ag_(6) leads to pronounced nonlinear optical response,paving a new way for the development of chiral optical materials.
