Abstract:
We demonstrate that three flexible MOFs termed FJI‐H11‐R (FJI‐H=Hong's group in Fujian Institute of Research on the Structure of Matter, R=Me, Et, i Pr) can reversibly respond to temperature and solvents via structural transformations, which can be visualized by in situ single‐crystal X‐ray snapshot analyses. FJI‐H11‐R exhibit colossal anisotropic thermal expansion, with a record‐high uniaxial positive thermal‐expansion coefficient of 653.2×10 −6 K −1 observed in FJI‐H11‐Me. Additionally, large c ‐axial shrinkage of 32.4 % is also observed during desolvation. The stimuli‐responsive mechanism reveals the structural evolutions are related to the rotations and deformations of the organic linkers.
