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).
