Three discrete tetrahedral metallo-supramolecular cages were designed and constructed using truxenepended base *** 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 *** particular,the anti-counterfeiting performance and emission behaviors of the cages in the solid state under external hydrostatic pressure were investigated.

The self-assembly of supramolecules driven by metal coordination has been intensely researched because of its extraordinary characteristics and potential applications. In my work, carbazole was utilized as the ligand backbone to construct supramolecular cages with Pd cations(Figure 1). When the di-monodentate ligand La reacted with the palladium salt [Pd(CHCN)](BF), a stable monomeric cage [PdLa] was achieved and the corresponding dimeric cage was obtained after the addition of stoichiometric amounts of halide anions. Surprisingly, excess amounts of the same anion leads to a second structural transition generating a triply-catenated link structure. In the other system, the tri-monodentate ligand Lb assembled with the same Pd-salt and a peanut-shaped cage [PdLb] was obtained. Furthermore, the cage [PdLb] could transform quantitatively into an interpenetrated dimer [PdLb] upon addition of chloride anions. Interestingly, it was found that the aggregates of [PdLb] could interact with polyanionic DNA in aqueous solution, which provides some insights with the application of supramolecular chemistry into the research of artificial histone mimics. In conclusion, carbazole-based supramolecular cages were successfully synthesized and the structural transformation was realized under different reaction partners.
