Synthesis of Novel Macrocycles Condensation of 1,4-dimethoxybenzene (DMB) with paraformaldehyde gave novel para-bridged pentacyclic pillar DMB (DMpillar[5]arene). Moreover, para-bridged pentacyclic hydroquinone (Pillar[5]arene) was prepared. Pillar[5]arene formed 1:1 host-guest complexes with dialkyl viologen and alkyl pyridinium derivatives. However, pillar[5]arene did not form complexes with diadamantyl viologen derivative, since bulky adamantyl group was unable to thread cavity of pillar[5]arene. Macrocyclic Host-Carbon Nanotube Hybrids We have developed hybrids of single-walled carbon nanotubes (SWNTs) and macrocyclic host compounds such as cyclodextrins, cyclodextrin-guest complexes, water-soluble calixarenes and cucurbiturils. Since these macrocyclic hosts form host-guest complexes with various kinds of guests, cavities of the macrocycles around SWNT are able to capture guest molecules on SWNT surface. By utilizing host-guest interaction between CDs on SWNT surface and polymers carrying guest moieties, supramolecular SWNT hydrogels were successfully prepared. The supramolecular SWNT hydrogel exhibited gel to sol transition by adding competitive guest and host. Moreover, by using the hybrids of water-soluble calixarenes and SWNTs, supramolecular polymers comprised of SWNTs were constructed. Hybrid Materials Based on Phenol Resin We have developed new functional phenol resin materials by hybridization with inorganic nanoparticles, ionic liquids and carbon nanotubes.
