Abstract: By postsynthetic modification method (PSM), chiral metal-organic frameworks(MOFs) were designed and synthesized. The L-proline derivative (Boc-L-ProCl) was anchored on the pore of Cr-MIL-101-NH2 by PSM method to gain a chiral MOFs (Cr-MIL-101-PaB2). 1H NMR spectra confirmed the yield up to 64% by twice process of PSM, and solid circular dichroism (CD) result showed that Cr-MIL-101-PaB2 was a chiral compound. Their structures were characterized by infrared spectroscopy (IR), nitrogen desorption-adsorption, thermogravimetry (TGA), powder X-ray diffraction (PXRD). The experimental results confirmed that synthesized chiral MOFs by PSM method for the needed purpose can avoid the self-assembly uncertainty of MOFs. |
