| Outline of Final Research Achievements |
A synthetic protocol for cyclooctatetraenes was developed by using formylbenzyl sulfones as starting compounds. The products showed a large solvent effect in photoluminescence and mechanochromism in the solid states. We developed a synthetic design for stimuli-responsive organic dyes by combination of planar pai-systems with large substituents. We prepared propyne equivalent which was easy-to-handle, and applied it to syntheses of arylpropynes which could be transformed largely expanded pai-systems. We demonstrated that consecutive desilylation and oligomerization in-situ prepared terminal ethynes.
