摘 要：Main observation and conclusion Magnifying the controllable directional motions of molecular machines to the macroscopic levels is a significant topic for *** metal–organic frameworks with long-range order and responsive structural transformation under external stimuli may be an appropriate platform for achieving the *** taking advantage of the single-crystal to single-crystal manner of soft porous crystals,we utilize single-crystal X-ray diffraction to directly observe the dynamic structural inversion of a new three-fold interpenetrated pillared-layer metal-organic framework[Co(edba)(bpy)](MCF-83,H2edba=4,4’-(ethyne-1,2-diyl)dibenzoic acid,bpy=4,4’-bipyridine).More interestingly,the dynamic inversions of the pillars and layers are selectively guest-controllable and independent,allowing precise control of the directional shape changes,which is the key of constructing intelligent materials to accomplish a complex *** mechanism is further studied by combining the X-ray diffraction analyses,sorption measurements and molecular simulations.
