Abstract Augmented reality (AR) displays have provided users with immersive and see‐through experiences by overlaying virtual information onto the real physical environment. To realize combination of information, holographic plastics hold great promise as a waveguide combiner due to their high diffraction efficiency, transmittance, ease processing. However, adoption in practical AR is significantly limited reliability. Herein, subtle design longline‐like polymers multiple “hooking” sites reported that can undergo crosslinking after manufacturing. The resulting plastic reflection grating structures not only exhibits efficiency (> 80%), transmittance ( T 400 > 80%) low haze (<3%), but also shows improved stability under various environmental conditions (e.g., 60 °C oven, 80 water, & 90% relative humidity chamber), finally enabling high‐fidelity display three‐primary colors. proven critical, control group without inferior despite holding very similar parameters before This work establishes viable paradigm for developing reliable combiners explores new optical application chemical design.

Abstract Luminescent switches with multiple optical outputs are essential for meeting the growing demand high‐security encryption. Herein, symmetric and chiral molecules designed synthesized by integrating luminescent planar Pt(II) moieties into SS / RR ‐trans‐1,2‐cyclohexane diamine scaffolds. This approach enables correlation of structures, assemblies, optical/chiroptical properties these materials, which exhibit spacer‐dependent chiroptical behavior. The more rigid foldamer shows unusual switching from monomer to intramolecular excimers corresponding circular dichroism circularly polarized luminescence increasing temperature, differing significantly conventional chromophores. Based on its reversible sensitive multicolor phosphorescence characteristics, molecular is employed create a stepwise anticounterfeit ink, advancing anti‐counterfeiting technology.

Reversible Photoresponsive Multicolor Fluorescent Carbon Dots for Repeatable Dynamic Information Encoding

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Photoresponsive carbon dots (CDs) materials have broad application prospects in fields such as ultraviolet (UV) light detection, advanced anticounterfeiting, and information encryption. However, developing color-tunable, photoresponsive CDs that can respond quickly reversibly remains a significant challenge. In this work, we successfully achieved multicolor fluorescence emission from by surface-modifying them with different concentrations of tetraethylenepentamine (TEPA), forming naphthalimide structures to UV light. Importantly, the response time reached fast 0.5 s, color reversibility was through simple shaking without need for additional stimuli. Research has shown generation is due formation on surface CDs, which produce radicals under continuous exposure. The TEPA lead varying amounts radicals, thereby affecting energy bandgap resulting changes. On basis differences times colors, further developed repeatable dynamic encoding system enables storage

Abstract The development of artificial light‐harvesting systems mimicking the natural photosynthesis method is an ever‐growing field research. Numerous such as polymers, metal complexes, POFs, COFs, supramolecular frameworks etc. have been fabricated to accomplish more efficient energy transfer and storage. Among them, coordination complexes (SCCs) formed by non‐covalent metal‐ligand interaction, shown capacity not only undergo single multistep migration but also utilize harvested for a wide variety applications photocatalysis, tunable emissive systems, encrypted anti‐counterfeiting materials, white light emitters This review sheds on behavior both 2D metallacycles 3D metallacages where design ingenuity has executed afford harvesting donor ligands well acceptors.
