| Outline of Final Research Achievements |
The march of polymer chemistry has enabled a precise synthesis of polymers with unique shapes, such as ring, star, ladder, etc., which has revealed that the polymer properties are determined by the shapes as well as their molecular weight, monomer structure, monomer sequence, monomer composition. However, as a general rule, it is challenging to create the unique shaped polymers that can switch their shapes. We thus postulate that specific host-guest complexation can frame the shape switchable polymers. To test the hypothesis, we chose to work with a calix[5]arene-fullerene complex, which shows very high binding selectivity and affinity between them.

本研究成果では，カリックス[5]アレーンとフラーレンの選択的会合体形成が，ポリマーの構造制御に有効であることを示した。また，この構造変換は熱や競合ゲスト分子を加えることにより，可逆的に起こることが分かった。ポリマーの物理物性はポリマーの形状に依存するため，自在に形状を制御することができれば，物理物性を自在に変換することのできる外部刺激応答性ポリマー材料への応用が期待される。
