Guest-adaptive molecular recognition by a double-walledcoordination cage

摘要

Conformational change around a recognition site upon guest binding is important forconstruction of dynamic chemical systems.In this study,we found that double-walledcoordination cage 1 exhibits the guest-adaptive molecular recognition and dynamicguest exchange.The characteristic double-walled knotted structure provides theexpandable cavity and portals,which allows for thermodynamic and kinetic guestselections.
