【摘要】 Metal-organic frameworks（MOFs） have attracted intensive attentions of chemists because of the advantages of ordered structures and promising applications over other porous materials.^[1] The numerous MOFs were prepared,in which various carboxylate ligands are always dominant research object.However,due to the weak M-O bonds,the most carboxylate-based MOFs possess poor water,acid and base chemical stability,thus confining their applications greatly as materials.’2’ The incorporation of azolate ligands give rise to a very effective strategy to build stable MOFs because of great robustness of M-N bonds.For these bags in MOFs,we recently have,on one hand,designed and synthesized a series of azolate ligands to construct some new metal-azolate frameworks,on the other hand,combined azolate and carboxylate mixed-groups to construct new metal-azolatecarboxylate frameworks,they disclose not only good stability but also excellent sorption and seperation,as well as luminescence properties.’3’ The incorporation of azolate and carboxylate mixed groups could offer a developmental approach to fabricate MOFs.更多还原
