Note
  As a new porous material, metal-organic framework (metal-organicframeworks,MOFs) has been widely used in sensing, gas storage, catalysis, due to its unique pore structure, large specific surface area, chemical and composition tunability. Molecular recognition, ion exchange and other functional materials. Introducing chiral molecules such as BINOL, Schiff base and metalloporphyrin into the framework of MOFs is an effective strategy for the synthesis of heterogeneous asymmetric catalysts and chiral separation.
Abstract

  The ligand 1,1-binaphthyl-2,2-dihydroxy-6,6-dicarboxylic acid was prepared by esterification, coupling and hydrolysis with 2-hydroxy-6-naphthoic acid as raw material, and synthesized by diffusion method. A new two-dimensional BINOL-Sr metal organic framework (MOF). The introduction of catalytically active chiral molecules BINOL, Schiff base, metalloporphyrin and other compounds into the framework of MOFs is an effective strategy for the design and synthesis of heterogeneous asymmetric catalysts and chiral separation.

Conclusion

 Using 6-hydroxy-2-naphthoic acid as raw material, esterification, coupling and hydrolysis, 2,2-dihydroxy-1,1-binaphthyl-6,6-dicarboxylic acid (H2L) ligand is obtained and diffused A novel two-dimensional BINOL-Sr(II) metal organic framework MOF(1) was synthesized. The complex MOF(1) is composed of one cesium ion, one ligand L and two water molecules [SrL( H2O)2]nnDMF, MOF(1) crystal has one one-dimensional channel in the a-axis direction, and the channel is filled with uncoordinated DMF guest molecules.
