| Outline of Final Research Achievements |
It has been predicted that polyhedral oligomeric silsesquioxane (POSS) has an electronic effect on the substituted conjugation units, but the detail remained to be understood because of the absence of practical synthetic methods for aryl-POSS. In this work, we have developed direct arylation reactions of POSS. These reactions were applied to obtain various kinds of aryl-POSSs for the investigation of their optical and electronic properties. That is, Pd- and Rh-catalyzed reactions were developed, and the reaction mechanism was elucidated by computational methods. The UV-vis absorption spectra of the aryl-POSSs and computational evaluation revealed the contribution of the POSS units to the conjugated systems.

三次元構造を持つ分子は、例えばフラーレンなど、特異な電子物性を示すことで産学を問わず幅広く研究が展開されてきた。かご型シルセスキオキサンは立方体構造というユニークな三次元構造体であり、極めて高い耐熱性・透明性を持った分子である。本研究では、これまで未解明であったかご型シルセスキオキサンの電子物性を明らかにする強力なツールを確立することに成功した。実践的な分子修飾法が確立されたことで、この分野にブレークスルーがもたらされ、新たな電子材料群の創出に貢献することにつながる。
