A Thermostable Three-Dimensional Homochiral Metal-Organic Framework Constructed from N-Rich Ligand: Syntheses, Crystal Structures, and Properties

By using the designed N-rich 3,6-bis(4-methyl-1H-imidazol-1-yl)pyridazine (b4mmp) and chiral d-camphoric acid (d-cam) ligands to react with cadmium acetate, a new bulk homochiral 3D metal-organic framework [Cd-2(d-cam)(2)(b4mmp)(DMF)](n) (1) has been synthesized. Compound 1 bears an uninodal 6-connected net structure with unprecedent topology, and it has a high thermostability. Moreover, the circular dichroism spectrum and photoluminescent properties for 1 were also investigated.
