Linker installation is a potent strategy for integrating specific properties and functionalities into metal–organic frameworks (MOFs). This method enhances the structural diversity of enables precise construction robust structures, complementing conventional postsynthetic modification approaches, by fully leveraging open metal sites active organic linkers at targeting locations. Herein, we demonstrated an insertion d-camphorate linker flexible Zr-based MOF, PCN-700, through installation. The resultant homochiral MOF not only exhibits remarkable stability but also functions as highly efficient luminescent material enantioselective sensing. Competitive absorption energy/electron transfer processes contribute to sensing performance, while difference in binding affinities dominates enantioselectivity. work presents straightforward route crafting stable MOFs
