摘　　要：Post-synthetic installation strategy is an effective approach to improve the functions of metal-organic frameworks(MOFs).Herein,a pair of chiral MOFs is successfully constructed through solvothermal subcomponent self-assembly and exhibit circularly polarized luminescence(CPL).These MOFs contain coordinatively unsaturated Zn sites and channels,which allow the installation of pyridyl-terminated pillars into the original structure.Such a post-synthetic installation process reinforces the MOFs'rigidity and increases the photoluminescence quantum yields(PLQYs).Furthermore,the luminescence dissymmetry factors(glum)of these post-modified MOFs are amplified after installing the pillars.This work provides an appealing strategy for boosting the CPL performance of chiral MOFs.
