A Controllable Gate Effect in Cobalt(II) Organic Frameworks by Reversible Structure Transformations

摘要

Materials that show reversible structure transformation and a characteristic response toward specific external stimuli are vitally important for applications in sensing, molecular capture, switches, and so on. In particular, any change of physical properties (such as color, magnetism, and electric resistance) associated with the transformation that could be monitored to indicate the state of these materials, are factors for sensor and other applications. Moreover, owing to the convenience and detail concerning solid-state structure transformation that can be obtained by diffraction methods, single-crystal to single-crystal (SC-SC) structure transformations of crystalline materials have become of importance and interest. In recent years, SC-SC structure transformations of different materials triggered by light temperature, and guest molecules have been reported. However, SC-SC dynamic structural changes involving breaking and forming of bonds are still rare, particularly for those examples with potential applications.
