| Outline of Final Research Achievements |
A series of novel double-stranded spiroborate helicates composed of oligophenol strands bearing photoresponsive, fluorescent, and metal coordination units in the middle and at both ends have been designed and synthesized. The cis-to-trans photoisomerization of the extended stilbene helicate with UV light further induced an extension of the helicate. It was revealed that the monomer and excimer emissions of the pyrene helicate were controlled during the extension and contraction motions. Moreover, the bipyridine helicate exhibited a unique metal ion-triggered spring-like motion.
