Lead‐Free Chiral Hybrid Metal Halides for Circularly Polarized Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, Volume 14, Issue 30, 14 August 2026.
Lead‐free chiral hybrid metal halides provide a versatile platform for realizing chiroptical responses through chiral modulation of metal–halide frameworks with diverse dimensionalities, induces inversion‐symmetry breaking and enables dissymmetric excited‐state transitions toward efficient circularly polarized luminescence and electroluminescence.

Effect of Alkyl Chain Length on the Bandgap, Ferroelectric, and Photoelectric Properties of Lead‐Based Molecular Ferroelectrics

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
This study develops a novel 2D molecular ferroelectric [C6N2H18]PbI4 with polarization enhanced photovoltaics. It systematically investigates the effect of alkylamine spacer cation chain lengths on the band gap, ferroelectric, and photoelectric properties, offering new design strategies.

Unity Quantum Yield of High‐Entropy Quantum Dots Composited With Photonic Crystals for Information Encryption

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
This study first extends the high‐entropy concept to I‐III‐VI quantum dots (QDs) and synthesizes CZCrGSe/ZnSe/ZnS core/shell/shell QDs with a record photoluminescence quantum yield (PLQY) of 100%. Their ZnSe/ZnS double shell efficiently passivates defects and boosts structural stability.

Halide/Pseudohalide Anion Regulation of Polar Structure and Glass‐Forming Ability Toward Polar Hybrid Glass‐Ceramic

open access: yesAggregate, Volume 7, Issue 8, August 2026.
Systematic anion engineering from halide to pseudohalide (Cl− → Br− → I− → NCS−) in a family of cadmium(II)‐based organic‐inorganic hybrids drives a progressive transition from centrosymmetric to polar structure, depresses melting point, reduces fragility index, and enhances glass‐forming ability, ultimately affording a polar hybrid glass‐ceramic with ...

Design, Synthesis, X‐Ray Crystallographic Characterization, Anticholinesterase and Antioxidant Evaluation, and Molecular Modeling of Novel Dispiroindene‐Pyrrolidine Derivatives as Multifunctional Anti‐Alzheimer Agents

open access: yesDrug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT A novel series of 5‐chloro‐N‐alkyl‐1′,1″‐dimethyl‐4′‐aryldispiro[indene‐2,3′‐pyrrolidine‐2′,3″‐indoline]−1,2″(3H)‐diones (4a–r) was rationally designed and synthesized via a one‐pot multicomponent reaction of N‐alkylated 5‐chloroisatin derivatives, 2‐(arylmethylidene)−2,3‐dihydro‐1H‐inden‐1‐ones (2a–i), and sarcosine (3).
