Synthesis, Crystal Structure and Circular Dichroism Property of a Homochiral Ni-MOF Based on D-Camphorate-Derived Enantiopure Ligand
A homochiral metal-organic framework, [Ni(D-L)(py)2(H2O)2]n (1) [D-H2L = 4,4′-[[(1R,3S)-1,2,2-trimethylcyclopentane-1,3-dicarbonyl]bis-(azanediyl)]dibenzoic acid], has been successfully synthesized based on D-camphorate-derived enantiopure ligand. 1 was characterized by single-crystal X-ray diffraction (SCXRD), powder X-ray diffraction (PXRD), Fourier transform infrared spectral analysis (FTIR), thermogravimetric analysis (TGA) and the circular dichroism (CD) spectrum. The experimental results show that 1 features a homochiral triple helix and is formed a 3D supramolecular framework by supramolecular interactions. In addition, the circular dichroism (CD) spectrum verifies the chirality introduction from the ligand to crystal. The successful preparation of the homochiral Ni-MOF provides more possibilities of employing the chiral ligand to produce various chiral MOFs.
Graphical Abstract
A homochiral Ni(II)-MOF 1 was prepared by using D-camphorate-derived enantiopure ligand under solvothermal condition, in which the chirality of 1 was confirmed by the circular dichroism (CD) spectrum
