Flexible metal–organic frameworks

摘要: Advances in flexible and functional metal–organic frameworks (MOFs), also called soft porous crystals, are reviewed by covering the literature of five years period 2009–2013 with reference to early pertinent work since late 1990s. Flexible MOFs combine crystalline order underlying coordination network cooperative structural transformability. These materials can respond physical chemical stimuli various kinds a tunable fashion molecular design, which does not exist for other known solid-state materials. Among fascinating properties so-called breathing swelling phenomena as function host–guest interactions. Phase transitions triggered guest adsorption/desorption, photochemical, thermal, mechanical stimuli. Other important MOFs, such linker rotation sub-net sliding, necessarily accompanied crystallographic phase transitions, briefly mentioned well. Emphasis is given on reviewing recent progress application situ characterization techniques results theoretical approaches characterize understand mechanisms transitions. The MOF systems, discussed, categorized type metal-nodes involved how their chemistry molecules controls framework dynamics. Aspects tailoring responsive mixed component solid-solution concept included, well examples possible applications separation, catalysis, sensing, biomedicine.
