Abstract Functional materials that exhibit circularly polarized luminescence (CPL) have shown immense potential in applications such as 3D optical displays and advanced information encryption. However, facile efficient regulation of the multiple emission properties chiral systems has remained a challenge due to scarcity suitable complexity systems. Herein, CPL platform is fabricated by helical co‐assembly an aldehyde‐functionalized fluorane dye (Rhodol‐CHO, 6′‐(diethylamino)‐3′‐hydroxy‐3‐oxo‐3H‐spiro[isobenzofuran‐1,9′‐xanthene]‐4′‐carbaldehyde) liquid crystals, which can efficiently combine stimuli‐responsive characteristics high activity. By introducing acid, base, compounds containing primary amino (─NH 2 ) groups, property system be easily modified. The obtained apparent asymmetry, with g lum values reaching 0.54–0.75). Further, these modules are successfully applied multi‐mode encryption, highlighting their practical utility. Therefore, this study presents novel strategy for developing diverse behaviors based on simple‐designed platform, advancing further materials.

In this work, we explored the potential of thiol-capped CdZnTe quantum dots (QDs) as an exceptional signal tag for fluorescence aptasensing applications. Employing a one-pot hydrothermal approach, modulated terminal functional groups QDs using l-cysteine (Lcys), 3-mercaptopropionic acid (MPA), and N-acetyl-l-cysteine (NAC) ligands. Our comparative analysis revealed that NAC-capped (NAC-CdZnTe QDs) exhibited superior anti-interference capabilities storage stability across various temperatures, pH levels, durations. Encouraged by these promising results, further optimized use ultrastable NAC-CdZnTe encapsulated in dendritic mesoporous silica nanoparticles (DMSN@QDs) development advanced aptasensor aflatoxin B1 (AFB1) detection. The developed DMSN@QDs tags achieved remarkable amplification approximately 10.2 fold compared to coated (SiO2@QDs) labeled aptasensor. This was able detect AFB1 within wide range 1 pg mL–1 200 ng mL–1, achieving limit detection low 0.41 (S/N = 3). Crucially, specific binding affinity between aptamer target enabled be easily customized targets simply replacing sequence with desired one. QDs, particularly when DMSNs, leads highly sensitive selective aptasensors targets, thereby, paving way advancements diverse

Printing materials with circularly polarized light (CPL) emission holds promise for flexible stereoscopic displays and multilevel anticounterfeiting solutions. However, a key challenge lies in developing printable CPL that exhibit both high photoluminescence quantum yield (PLQY) luminescence dissymmetry factor ( g lum ) values. In this study, we present the macroscopic controllable production of efficient full-color carbon dot (CDs) photonic paint materials. These materials, consisting heavy metal-free CDs as emitters, liquid crystals host matrices, are produced using helical coassembly strategy. Our systems based on achieve PLQY (more than 80%) values 1.4), figure merit (a performance indicator properties calculated by multiplying glum) 1.12, outperforming other material systems. Furthermore, CDs-CPL is successfully used printing luminous patterns features. This research provides insights into advanced highlighting their broad potential applications.
