| Outline of Final Research Achievements |
Metal organic frameworks with flexible structures (soft MOFs) show a unique adsorption property, which is called as "gate adsorption". In the present study, we used ZIF-8 and ZIF-67 as a model system. We synthesized core-shell type ZIF particles and investigated their adsorption properties. Our experiments demonstrated that a microreactor with an excellent mixing performance enabled the synthesis of uniform core-shell particles. In addition, we found that the existence of the interfaces between core and shell domains induced cooperative structural transition of ZIF framework to result in a adsorption behavior that is not described by those of single component ZIF-8 and ZIF-67 particles.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では，Soft MOFが示す構造転移に起因する特異な吸着挙動を制御し，所望の条件での構造転移を示す材料設計指針の確立を目指している。錯体微粒子の化学組成を試行錯誤的に変える従来の試みとは全く異なり，粒子径・形状の制御および結晶複合化による相乗的な構造転移制御，そして，それにより吸着特性制御を目指すというアプローチは，特性制御手法の新たな可能性を示すものである。本研究の成果をもとにすれば，常圧でのガス貯蔵と環境に応答した吸着・脱着を可能とするスマート吸着材や，精密なゲート吸脱着圧制御に立脚した分子センサー，分子モーターの創製などが見込まれ，多様な分野への波及効果が期待される。
