Article Abstract
The aggregation-induced emission (AIE) mechanism of restriction of double-bond rotation (RDBR) was utilized to design an excellent solid emitter and sensor for the first time. Thus, -tetraphenylethylene (TPE) macrocycle diammoniums were synthesized and bound to a DNA chain by its two ammonium arms. The formed TPE dicycle at the position restricted the rotation of the double bond in both the ground and excited states, resulting in AIE enhancement, chiroptical performance enhancement, and sensing enhancement.

Circularly polarized luminescence (CPL) has emerged as a critical technology for anticounterfeiting and optical display applications due to its unique chiroptical properties. We report a multicolor CPL-emitting elastomeric film (P37/PSK@SiO-PDMS) that synergistically combines chiral helical polyacetylene (P37) and a surface-engineered perovskite (PSK@SiO) through hydrogen-bond-directed assembly. Confinement within the PDMS matrix drives P37 to self-assemble into a chiral supramolecular structure through hydrogen bonding, inducing a chiroptical inversion.

Spherical chiral polyrotaxanes (CPRs) with steerable circularly polarized luminescence (CPL) are intriguing as advanced chiroptical materials but have not been reported to date. Here, we constructed spherical chiral polyrotaxane (CPR) materials with steerable CPL by utilizing cyclodextrins (α-, β-, or γ-CyD) as the chiral wheel. Importantly, the structure and the CPL performance of the CPR materials can be regulated by varying the feeding amount and the type of cyclodextrin (α-, β-, or γ-CyD).

Expanded helicenes are interesting compounds created by modifying the original helicene structure through the incorporation of linearly fused benzene rings, enlarging the helical diameter. Motivated by Tilley et al.'s report of a key expanded helicene structure in 2017, several research groups have synthesized such nonplanar aromatic compounds, aiming to explore their impressive structures, properties, and chiroptical performance.

Long-range ordered chiral nanoparticle superstructures, formed colloidal self-assembly, exhibit geometrically asymetric structures-such as helices, twisted arrangements, or lattices with low-symmetry space groups-endowed with distinctive chiroptical properties. This review highlights that spherical inorganic nanoparticles typically require chiral templates (, supramolecular polymers, DNA, proteins or liquid crystals) to induce asymmetric spatial organization. In contrast, anisotropic inorganic nanoparticles (, nanorods, tetrahedra, or nanodumbbells) can achieve chiral assembly both with and without templates, the latter driven by interfacial directional forces or geometric curvature matching.

A series of stable electro-switchable cellulose nanocrystal (CNC) films is fabricated by the covalent functionalization of preassembled chiral nematic CNC substrates with electro-active molecules. Through this approach, we anchor siloxy-group-containing viologens (SV) to the surface of CNCs in a preformed film. Unlike conventional premixing strategies that typically disrupt chiral self-assembly of CNCs, this method produces films that retain the structural color and chiroptical properties of the chiral nematic CNC substrate, while exhibiting stable electrochromic performance.
