Naphthyridine‐Based Donor–Acceptor Boron Difluoride Complexes Targeting Red Emission in Organic Light‐Emitting Diodes

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

A Proline‐Integrated Donor–Acceptor Fluorophore: Water‐Vapor‐Responsive Mechanochromic Luminescence and Latent Fingerprint Visualization

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
A proline‐integrated donor–acceptor fluorophore enables multifunctional luminescence through rational molecular design. Water‐vapor‐responsive mechanochromic luminescence (MCL) with circularly polarized luminescence (CPL) switching and efficient visualization of latent fingerprints (LFPs) are realized from this single small organic molecule.

Polymer‐Based Passive Radiative Cooling A Structural Design Perspective

EcoMat, Volume 8, Issue 7, July 2026.
This work categorizes structure‐oriented design strategies for polymer‐based passive radiative cooling into fibrous, porous, photonic/meta, and hybrid composite architectures. Each structural motif is shown to regulate solar scattering, infrared emissivity, and heat transport through distinct geometry‐driven mechanisms, offering a systematic pathway to

Photonic Crystal Stimuli-Responsive Chromatic Sensors: A Short Review

Micromachines, 2020
Photonic crystals (PhC) are spatially ordered structures with lattice parameters comparable to the wavelength of propagating light. Their geometrical and refractive index features lead to an energy band structure for photons, which may allow or forbid ...

Mechanoluminescent Mixed‐Anion Borate Sr2B5O9Cl:Eu for Dynamic Anticounterfeiting

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Mechanoluminescence (ML)—the emission of light in response to mechanical stimuli—offers a direct and visually intuitive route for transducing mechanical information into optical signals. Herein, we report a mixed‐anion strategy to prepare mixed‐anion borate Sr2B5O9Cl:Eu phosphors through a facile, low‐temperature, and ambient‐atmosphere solid ...

Revisiting Cu(I)‐Dppm Chemistry: Bright Thermally Activated Delayed Fluorescence Luminescence, Anion Dependance, Mechanochromism, and Singlet Oxygen Generation of a Dinuclear Cu(I) Homoleptic Complex

ChemistryEurope
The one‐step syntheses of highly luminescent Cu(I) dimetallic complexes are reported using Cu(I) salts and the commercially available dppm ligand. Three crystalline phases A–C, obtained either with PF6− (A and B: [Cu2(μ2‐dppm)3](PF6)2) or TEF− (C: [Cu2 ...
