Outline of Final Research Achievements

Organic molecules involved in living things and plastics are composed of chemical bonds between carbon atoms. Such a structure containing sequential bonds between the same elements is called a homocatenate structure. In nature, we find homocatenate structures of sulfur as well as carbon. Moreover, synthetic chemists have achieved the synthesis of homocatenate silicon and germanium. However, homocatenate polymers of the group 13 elements, such as boron and aluminum, have not been realized. Herein, this research focused on the development of novel reactions required for the synthesis of homocatenate aluminum compounds. The synthetic approach involves three distinct steps. The first step has been accomplished as the result of this project.

Academic Significance and Societal Importance of the Research Achievements

ホモカテネート(HC)構造とは同一元素が共有結合で連結した構造を指し、13~16族元素で形成可能とされる。13族は唯一この構造の報告がなく、高分子科学における未踏領域である。非炭素HCの特徴に結合を介して電子が広がるというものがある。この特徴を使うと、スマートフォンなどのデバイスの小型化につながると期待される。しかし、13族元素HCが実現されておらず、HCの物性が未解明であり、応用研究の足かせになっている。本研究がさらに進展することで、13族HCが実現されることで、HCを基盤とした機能性材料の創出のために必要な新たな学理の構築につながる。
