Multicomponent construction of the tetrakis(spiroborate) anionic nanocycles was achieved by reacting bis(dihydroxynaphthalene)s with tetrahydroxyanthraquinone in the presence of boric acid in a self-organized manner. These nanocycles exhibited selective molecular recognition behavior toward cationic guests such as methyl viologen derivatives. Formation of a supramolecular ring@ring and a guest@ring@ring structure was observed by combining the anionic nanocycle and the vinylogous analog of cyclobis(paraquat-p-phenylene).
通过在硼酸存在的条件下，使双(二羟萘基)与四羟基蒽醌自组装反应，实现了四(螺硼酸盐)阴离子纳米环的多组分构建。这些纳米环对阳离子客体如甲紫精衍生物表现出选择性的分子识别行为。通过结合阴离子纳米环和环双(对醌-对苯撑)的乙烯基类似物，观察到超分子环@环和客体@环@环结构的形成。
