Abstract：

Herein　the　chiral　resolution　of　racemic　Zr4L6　tetrahedral　cages　has　been　realized　using　luminescent　enantiopure　coordination　cations.　Accordingly,　anionic　ΔΔΔΔ-Zr4L6　and　ΛΛΛΛ-Zr4L6　cages　(L　=　embonate)　were　completely　resolved　using　enantiopure　[Ag(R-BINAP)2]+　and　[Ag(S-BINAP)2]+　cations,　respectively,　and　a　pair　of　pure　enantiomers　(PTC-374(R,Δ)　and　PTC-374(S,Λ);　PTC　=　polynuclear　titanium　cage)　were　easily　prepared　and　structurally　well-characterized,　featuring　an　uncommon　cage-supported　supramolecular　framework　with　zeolitic　SOD　topology.　The　stepwise　transfer　of　homochirality　can　be　clearly　observed　in　the　unusual　resolution　process.　Moreover,　the　perfect　combination　of　two　functional　components　endows　such　co-assembled　materials　with　synergistic　circular　dichroism　performance,　enhanced　fluorescence　and　circularly　polarized　luminescence　response.　©　2024　The　Royal　Society　of　Chemistry
