摘要
Abstract The chiral feature of γCD‐MOF, and especially the emergent cubic void, was not unveiled so far. Now, through the host–guest interaction between γCD‐MOF and achiral luminophores with different charges and sizes, the unique cubic chirality of the emerging void in γCD‐MOF as well as a size effect on CPL induction are revealed for the first time. Numerous achiral luminophores could be integrated into γCD‐MOF and emitted significantly boosted circularly polarized luminescence. While the small sized luminophores preferred to be loaded into the intrinsic void of γCD, large ones were selectively encapsulated into the cubic void. Interestingly, when the size of the guest luminophores was close to the cube size, it showed strong negative CPL. Otherwise, either positive or negative CPL was induced.
