研究内容 |
SURMOFナノシートのその場合成技術として、リガンドと競争的に配位可能な揮発性分子（酢酸など）の気相共存下、比較的低い温度で熱処理する”その場”再結晶化法を開発した。このソフト結晶化技術を、閉鎖空間での配位高分子構造体のエピタキシャル成長技術に応用する。穏やかな条件で平衡性を高めた条件での液相中での再結晶化によって、面内、面間、基板表面にアシンメトリーを導入した新たなアシンメトリー配位高分子を開発する。対称性の崩れた表面・空間を基盤とした再結晶化によって、多孔性配位高分子材料に様々なアシンメトリーの導入を試みる。(1)対称性の高いMOF結晶構造の中で、非対称性リガンドがキラリティを含めた新たな規則性を生み出し得るか？(2)単純な二次元平面にとどまらず、様々な対称性の崩れたアシンメトリー表面や空間を足場として、多孔性配位高分子のユニットセル自身に捻れを導入することが可能か？というチャレンジングな課題に挑む。 |
