Abstract

Interaction between heterogeneous, nanometer-sized building blocks (NSBBs) is fascinating from viewpoints of both structures and functions. We report the co-assembly of fullerene C₆₀ and a chiral silver nanocluster (Ag₆), which yields C₆₀ nanoarchitecture decorated with a small amount of Ag₆. While Ag₆ exhibits circular dichroism (CD) signal mainly in the ultraviolet (UV) region, the signal of the C₆₀-Ag₆ 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 C₆₀ crystal. The successful chirality transfer from the guest of Ag₆ to C₆₀-dominated supramolecular system indicates that the “sergeants and soldiers” effect is valid in architectonics of NSBBs. In addition, the doping of Ag₆ leads to pronounced nonlinear optical response, paving a new way for the development of chiral optical materials.

富勒烯 C60 纳米结构中的手性金属纳米团簇：手性转移和非线性光学特性的改善

从结构和功能的角度来看，异质纳米级构筑模块（NSBBs）之间的相互作用都是令人着迷的。我们报告了富勒烯 C60 与手性纳米银簇（Ag6）的共组装，从而产生了装饰有少量 Ag6 的 C60 纳米结构。Ag6 主要在紫外线（UV）区域显示圆二色性（CD）信号，而 C60-Ag6 混合物的信号则延伸到可见光区域（700 纳米以上）。可分辨出多达五对 CD 信号，这些信号与 C60 晶体的吸收非常吻合。从 Ag6 客体到 C60 主导的超分子体系的成功手性转移表明，"军士 "效应在 NSBB 的结构中是有效的。此外，Ag6 的掺杂导致了明显的非线性光学响应，为手性光学材料的开发铺平了新的道路。
