Naphthyl-bridge bis(β-cyclodextrin) (1) was synthesized via "click chemistry", and its self-assembly behavior was investigated by NMR, UV-vis, circular dichroism spectra, transmission electron microscopy, and atomic force microscopy. The results obtained indicate that the coordination of Hg(2+) with triazole rings in 1 induces the naphthyl moiety to move from being a self-included complex to the formation of nanoparticles through intermolecular self-aggregation. Furthermore, the formation and disassembly of nanoparticle was reversibly controlled by adding or removing Hg(2+).
萘桥联双（β-环糊精）（1）通过“点击化学”合成，并通过 NMR、UV-vis、圆二色光谱、透射电子显微镜和原子力显微镜研究了其自组装行为。结果表明，Hg（2+）与 1 中环三唑环的配位诱导萘基部分从自包含复合物通过分子间自组装移动到纳米颗粒的形成。此外，通过添加或去除 Hg（2+）可实现纳米颗粒的形成和拆卸的可逆控制。
