Upon similar treatment of thiophenes, the efficient generation of key 1,4-dianions occurs by means of desulfurative dilithiation with lithium powder, and the subsequent trapping of the dianions with electrophiles affords a vari-ety of exotic heterocycles including boroles, which represents a new addition to the chemistry of aromatic metamorphosis.本研究課題では，超分子科学特有の錯体を高分子材料の架橋点として導入し，新たな機能を有する高分子材料の創製を目指した．可逆的な架橋が導入された高分子材料は分子接着性や材料強度が回復する自己修復性を示した．この分子接着性を利用して，無機材料と有機材料の直接接着に成功した．分子接着性材料を用いた異種材料の接合の特徴は，線膨張率の異なる材料でも安定した接着機能を実現できる．また可逆性架橋を導入した高分子材料は靭性を向上したり，材料に蓄積された応力ひずみや強度からの回復を実現することができた．さらに可逆的結合に基づいたリサイクル特性や修復性を持った塗膜を実現した．The research project focused on a creation of polymer materials with innovative functions by introducing su-pramolecular complexes as a cross-linking point of the materials. The polymer materials with reversible cross-linking showed self-healing properties that exhibit molecular adhesiveness and restoring material strength. To utilize the molecular adhesiveness, we succeeded in direct bonding between inorganic and organic materials. The important point of dissimilar materials adhesion using a molecular adhesive can realizes stable bonding functions even in different linear expansion coefficient. Furthermore, the polymer materials with re-versible cross-linking improve toughness and recover from the stress-strain and strength accumulated in the material. Based on the functional properties, we have realized a repairable coating film and recyclability.本提案研究では，上記の単結晶酸化物ナノワイヤ研究を飛躍的に発展させる“堅牢な分子認識界面”を“分子形状記憶機能”を付加することで単結晶酸化物ナノワイヤ表面に実現する．本研究のアプローチでは，従来はソフト界面のみが特異的に実現すると考えられてきた分子認識界面を“単結晶ナノワイヤ表面 の分子形状記憶機能”という新しいコンセプトで堅牢な電気的分子識別を実現する．In this proposed research, a “robust molecular recognition interface” that dramatically develops the above-mentioned single crystal oxide nanowire research is realized on the surface of the single crystal oxide nanowire by adding a “molecular shape memory function”. In the approach of this research, the molecular recognition interface, which was conventionally thought to be specifically realized only by the soft interface, is realized by a new concept of “molecular shape memory function on the surface of single crystal nanowires” to realize robust electrical molecular identification.
