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).

Iron-catalyzed cross-coupling reactions of alkyl grignards with aryl sulfamates and tosylates

The iron-catalyzed cross-coupling of aryl sulfamates and tosylates has been achieved with primary and secondary alkyl Grignards. This study of iron-catalyzed cross-coupling reactions also examines the isomerization and β-hydride elimination problems that are associated with the use of isopropyl nucleophiles. While a variety of iron sources were competent in the reaction, the use of FeF3·3H2O was critical to minimize nucleophile isomerization.
Synthesis and characterization of liquid crystalline semiconducting materials, dialkyl-2-phenylnaphthalene derivatives - Mesomorphic behavior and charge carrier transport

For establishment of high electronic change carrier transport at ambient temperature, dialkyl derivatives of 2-phenylnaphthalene have been synthesized and characterized their liquid crystalline behaviors and photoelectrical properties. These materials exhibited smectic masophases (Smectic A, B and E phases), at fairly low temperature range extended down below ambient temperature. Fast electronic transport of positive carriers was observed in SmE phase, of 2-(4′-octylphenyl)-6-butylnaphthalene at 30°C, whose mobility was over 10-2 cm2/Vs.
