Circularly polarized luminescence (CPL) properties are investigated for pillar[5]arene, a chiral macrocycle with stable planar chirality, and its combination with a rod-shaped π-conjugated molecule. In tetrahydrofuran/H₂O, the two components form co-aggregate due to a hydrophobic effect. The co-aggregate affords low-energy photo-absorption and luminescence, which is effectively polarized with the highest CPL dissymmetry factor of 2.9 × 10⁻² among pillar[n]arenes.

The assembly of chiral structures using superatoms as building blocks is reported for the first time. The success of this assembly depends on the bonding properties of superatoms, leading to the emergence of a distinct form of chirality named “superatomic-based chirality”. With the abundance of superatoms, there is considerable anticipation for the significant expansion of chiral structures at the atomic level.

A pair of metalated tetraphenylethylene-based organic cage enantiomers have been successfully synthesized and characterized.

These findings provide unique insights to the interfacial emission properties of host–guest nano-luminophores.

The ternary co-assembly of L-GSH, AgNO₃, and an AIEgen TPA-Py is highly precise and specific through an extensive study about their analogues, which gives a fast and visual signal output by dramatic fluorescent enhancement. The ternary co-assembly show unique chirality sense, which suggests that the molecular chirality of L-GSH is transferred and amplified into the supramolecular helicity level.

Recently polymers become excellent candidates to construct artificial chiral aggregates, due to the diverse conformations and components.

We report the first nano-splitters containing aggregation induced emission luminogens prepared via polymerization-induced self-assembly of block copolymer. When added into the supersaturated solution of racemic amino acids with seeds, the fluorescent labeled nano-assemblies enantioselectively dyed the S-crystals and enabled the separation from colorless R-crystals in terms of fluorescent difference. Both enantiomers were obtained with high optical purity and yield. Owing to a low detection limit of fluorescence, the addition amount was reduced to 0.03 wt% without remarkably compromising the ee values of both enantiomorphs. Combining with low addition amount and efficient synthesis, the output-input ratio can be increased greatly.
