The occurrence and transmission of chirality is af ascinating characteristic of nature.H owever,t he intermolecular transmission efficiency of circularly polarized luminescence (CPL) remains challenging due to poor throughspace energy transfer.W er eport au nique CPL transmission from inducing the achiral acceptor to emit CPL within as pecific liquid crystal (LC)-based intermolecular system through ac ircularly polarized fluorescence resonance energy transfer (C-FRET), wherein the luminescent cholesteric LC is employed as the chirality donor,a nd rationally designed achiral long-wavelength aggregation-induced emission (AIE) fluorophore acts as the well-assembled acceptor.Incontrast to photon-release-and-absorption, the chirality transmission channel of C-FRET is highly dependent upon the energy resonance in the highly intrinsic chiral assembly of cholesteric LC,a sv erified by deliberately separating the achiral acceptor from the chiral donor to keep it far beyond the resonance distance.T his C-FRET mode provides ad enovos trategy concept for high-level information processing for applications such as high-density data storage,c ombinatorial logic calculation, and multilevel data encryption and decryption.

Development of circularly polarized luminescent (CPL) materials with strong emission and high dissymmetry factor of luminescence (g lum) is highly desirable. A series of CPL-active aggregation-induced emission luminogens (AIEgens) have been successfully constructed by incorporating AIEgen dicyanodistyrylbenzene (DCS) into chiral molecule cholesterol. Benefiting from its typical AIE characteristic, DCS allows emission efficiency up to 73.7% in a condensed state. Furthermore, cholesterol units ensure forming chiral liquid crystal in syntax, and increasing the g lum value of CPL from 7 × 10–4 for the amorphous state to 1.1 × 10–1 for the liquid crystal state. This approach paves a general avenue for addressing the major defect well: high g lum always suffers from suppression of emission efficiency.

A temperature-sensitive Förster resonance energy transfer system was constructed using a highly emissive liquid crystal co-assembled with Nile red, enabling thermo-optical modulation for controlling and directing light in stimuli-responsive devices.

Development of pure organic room‐temperature phosphorescent (RTP) materials with strong emission and decent processability is highly desirable. However, in the pursuit of high quantum yield (QY) of phosphorescence, the processability of RTP materials is suppressed unwarily. Here, a liquid crystalline (LC) copolymer is envisioned, NpA‐Chol, comprising bromonaphthalimide as the phosphor and cholesterol as the LC mesogen. NpA‐Chol exhibits LC flexibility at high temperatures, thus enabling the material to possess decent processability. In addition, the liquid crystallinity of NpA‐Chol could be improved remarkably after thermal annealing, making a 7.5‐fold increase in phosphorescence QY. This cholesterol copolymerization strategy paves a general avenue for addressing the major defect well: highly efficient RTP materials always suffer from suppression of thermal processability.

Light is essential to all life on the earth. Thus, highly efficient light‐harvesting systems with the sequential energy transfer process are significant for using solar energy in photosynthesis. For developing an efficient light‐harvesting system, a liquid aggregation‐induced emission (AIE) dye TPE‐EA is obtained, as a donor and solvent, which can light up the aggregation caused quenching (ACQ) Nile Red (NiR, acceptor) to construct a quantitative Förster resonance energy transfer (FRET) system in NiR⊂TPE‐EA. Impressively, this FRET pair shows an impressive photothermal effect, producing a peak temperature of 119 °C while excited by UV light, with 37.8% of conversion efficiency. NiR⊂TPE‐EA is quite different from most other photothermal materials, which require excitation with long wavelength light (>520 nm). Therefore, NiR⊂TPE‐EA firstly converts the solar into thermal energy and then into electric energy to achieve sequential photo‐thermo‐electric conversion. Such sequential conversion, suitable for being excited by sunlight, is anticipated to unlock new and smart approaches for capturing solar energy.
