| Outline of Final Research Achievements |
In this research, we focused on (1) the elucidation of the mechanism of a new boron-mediated aromatic ring construction reaction and (2) the development of π-conjugated functional materials. Through experimental and theoretical studies, we succeeded in the evaluation of the boron-mediated 1,2-carboboration of alkynes and the oxidative deborylation/C-C coupling of the resultant borepin derivatives. We also clarified the structural elements of 9-borafluorenes required for the efficient benzannulation of alkyne derivatives. Using the optimized reaction conditions and substrates, we have developed a dynamic propeller molecule with superb chiral sensing capability and a direct transformation reaction of linear π-conjugated polymers into microporous zigzag-shaped polymers. These findings would be useful for the development of new π-conjugated materials with unique structural and dynamic properties.
