Indolo‐Fused MR‐TADF Materials and their Application in Organelle‐Targeted Bioimaging

Advanced Functional Materials, Volume 36, Issue 63, 6 August 2026.
Using indolo‐fusion and sulfur bridging, four multi‐resonance thermally activated delayed fluorescent (MR‐TADF) materials are reported based on the quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) framework. Functionalization of these dyes with phosphonium groups enables cellular imaging with mitochondrial targeting in glassy organic nanoparticles ...

Engineering Energy Harvesting Pathways in Mn‐Yb‐Doped Perovskite Nanocrystals

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
Mn‐Yb codoping in metal halide perovskite nanocrystals establishes dual‐channel energy reservoirs that capture charge carriers and drip‐feed them back to the host on millisecond timescales. This synergistic recycling mechanism overcomes prompt nanosecond recombination limitations, enabling an eight‐fold enhancement in photocatalytic CO2​ reduction ...

White Light Emission and Energy Transfer in Mixed‐Metal Europium/Terbium/Thulium Formate Metal–Organic Frameworks: Effect of Lanthanum Dilution

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
A series of Eu3+, Tb3+, Tm3+ and La3+ formate‐based (mixed)metal‐organic frameworks were synthesized and investigated for energy transfer and white‐light emission. Efficient Tb3+→Eu3+ transfer enabled tuneable luminescence, while Tm3+ incorporation afforded near‐white emission.

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

Advanced 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. This

Fluorescence Tuning of Carbon Dots from Red to Blue via UV‐Induced Photochemical Etching

Advanced Science, Volume 13, Issue 43, 3 August 2026.
A UV‐driven photochemical process enables continuous color evolution of carbon dots from red to blue using a single irradiation parameter. Progressive photoetching restructures graphitic domains and surface states, allowing full visible‐spectrum emission control.

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

Aggregate, 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 ...

Self‑Protective Carbonized Polymer Dots Enabling Ultralong Room‑Temperature Phosphorescence in Strong and Tough Flexible Gels

Aggregate, Volume 7, Issue 8, August 2026.
The trade‐off between intersystem crossing and triplet exciton stabilization in PVA‐based self‐protective CPDs is resolved by tuning the alcoholysis degree of PVA. Using PVA with 88% alcoholysis affords NCD88 with an ultralong RTP lifetime of 1.05 s.
