“…Crystal engineering of solid coordination frameworks (SCFs) [1][2][3][4] has received a lot of interest during the past decade, not only for their potential applications as functional materials in gas storage, [5][6][7] gas separation, [8][9][10] heterogeneous catalysis, [11][12][13] drug delivery, [14][15][16] chemical sensing, 17,18 nonlinear optics 19 and biomedical imaging, 20,21 but also for their fascinating variety of structural topologies and flexible response to external stimuli. 22,23 Thus, many interesting solid-state transformations 24 of SCFs can be induced by light, heat, guest removal, uptake or exchange, expansion or reduction of the coordination sphere, oxidation of metal centers, condensation, or reactions between the ligands. 25,26 Due to changes in the coordination sphere, it is worth noting that removal/uptake of a ligand can induce local distortions that can extend along the whole framework.…”
