Salt metathesis in three dimensional metal-organic frameworks (MOFs) with unprecedented hydrolytic regenerability

摘要

Eight Zn-based porous (1.2 nm) homochiral MOFs (ValZnX, AlaZnX, X = Cl~-, Br~-, HCO_2~- and CH_3CO_2~-) were synthesized which possess extremely rare zeolrtk (unh) topology. These MOFs show an unprecedented hydrolytic regenerability. Salt metathesis reaction performed on these 3D MOFs in water resulted in 2D coordination polymers (CPs). Metal-Organic Frameworks (MOFs),constructed by coordination bonds between metal ions and organic linkers, have attracted researchers attention owing to their high gas (CO_2, H_2, CH_4 etc.) sorption, catalysis and separation.
