Circular Polarized Light Emission in Chiral Inorganic Nanomaterials

Shuang Jiang et al.

Summary: Chiral inorganic nanostructures have a strong interaction with photons, leading to a change in their polarization state and the emission of circularly polarized light. Understanding these polarization effects is important for various chemical and biological processes, as well as the development of chiral photonics. The interpretation of these effects is dependent on the structural parameters of the nanostructures, and there are different types of nanomaterials that exhibit either dominant circularly polarized luminescence or circularly polarized scattering.

Refractive Index-Adaptive Nanoporous Chiral Photonic Crystal Film for Chemical Detection Visualized via Selective Reflection

Avinash Kumar Rella et al.

Summary: Photonic crystals have great importance in technology, especially in optics and photonics. The authors report on refractive index adaptive photonic crystals, where the structural color responds to chemicals by changing the reflective color. Loading various chemicals into nanopores significantly shifts the structural color based on the chemical's refractive index. This sensing mechanism offers advantages such as durability, sensitivity, fast response, and wide detection range.

Supramolecular Polymers with Photoswitchable Multistate Fluorescence for Anti-Counterfeiting and Encryption

Jia Tang et al.

Summary: In this study, novel photoswitchable multistate fluorescent supramolecular polymers (PMFSPs) were prepared via host-guest interactions under a facile ultrasonication strategy. By adjusting the stimulation wavelength and utilizing photoinduced fluorescence resonance energy transfer (FRET), the supramolecular polymers can undergo reversible tristate fluorescence switching among none, red, and green. Due to the high contrast, rapid photoresponsiveness and prominent photoreversibility of the prepared PMFSPs, they have great potential in advanced anti-counterfeiting and multilevel information encryption.

Summary: Studying the photoluminescence properties of organic molecules in solid and solution states is crucial for understanding Aggregation Caused Quenching (ACQ) and Aggregation Induced Emission (AIE) behavior, as well as the mechanism of molecular luminescence. A hydrogen-bonded dimer with imperative interaction (CN)pi-7 pi(Ar) was designed and synthesized, and it was found that the (AIE) or (ACQ) effect can be tunable depending on the intermolecular interaction in the system. The impacts of steric, conjugation, and electronic effects on the ACQ/AIE properties were analyzed through crystallography, optical spectra measurements, and theoretical calculations.
