Chiral coordination molecular cages/capsules with discrete nanoconfined chiral cavities demonstrate significant potential applications across various fields.In this study,we utilized Tr?ger's base as the building block to design and synthesize two pairs of enantiopure ligands.These ligands were then self-assembled with Pd(II)ions through chiral self-sorting coordination,resulting in the formation of two pairs of homochiral M2L4-type coordination molecular capsules.Notably,due to differences in the substitution positions on the Tr?ger's base,these two pairs of enantiomeric coordination molecular capsules exhibited distinct levels of cavity closures,cavity sizes,and host-guest recognition properties.This research offers valuable insights into the construction of novel chiral molecular capsules and the regulation of confined cavities.
