摘　　要：Three discrete tetrahedral metallo-supramolecular cages were designed and constructed using truxenepended base ligands.Owing to the synergistic rigidifying effect of unsymmetric cyano-substituted oligo(pphenylene-vinylene)(u-COPV)suspended by the truxene skeleton,the resulting supramolecular cages were confirmed to exhibit significant aggregation-induced emission(AIE)accompanied by an interesting solvatochromic fluorescent behavior as well as a porous honeycomb-like state during aggregation.In particular,the anti-counterfeiting performance and emission behaviors of the cages in the solid state under external hydrostatic pressure were investigated.
