1. UV management by luminescent down-shifting for efficient and stable photovoltaics.
PMID:日期:2026-09-25As emerging photovoltaics move from record efficiencies toward practical deployment, simultaneously improving power conversion efficiency and long-term stability has become a central challenge. UV spectral conversion has attracted growing interest as a photonic management strategy. In this review, we summarize recent progress in UV-to-visible luminescent down-shifting (LDS) materials for high-efficiency crystalline silicon, perovskite, and organic solar cells. We show that the primary role of LDS is to alleviate short-wavelength spectral mismatch and parasitic absorption while suppressing UV-induced degradation through spectral shifting. Accordingly, device performance depends not only on selective UV absorption, photoluminescence quantum yield, Stokes shift, reabsorption loss, and emission-external quantum efficiency matching, but also on long-term UV durability. Furthermore, we compare the advantages and limitations of rare-earth systems, quantum-dot systems, organic molecule/polymer systems, and multifunctional composites, and then examine the functions of external coatings, encapsulation-integrated layers, antireflection/light-trapping coupled structures, and buried-interface integration. Taken together, these advances suggest that future progress will rely on the development of integrable, manufacturable, and weather-resistant front-end photonic management layers that combine UV-to-visible conversion with antireflection, directional scattering, encapsulation barrier properties, and interface protection, thereby enabling concurrent improvements in both efficiency and stability.

2. Net fluorine atom transfer from the perspective of a PCET chemist.
PMID:日期:2026-09-25Proton coupled electron transfer (PCET) reactions, which encompass hydrogen atom transfer (HAT), concerted proton coupled electron transfer (cPCET) and stepwise variations, have been studied in great detail. This has facilitated the thorough understanding of relevant enzymatic transformations and the efficient development of synthetic strategies. Despite the clear similarities between halogen atom transfer (XAT) and HAT, the conceptual framework used within the PCET community has not yet been extended to radical halogen reactivities. In light of a recent report showing that net homolytic C-F bond cleavage can proceed through a concerted electron fluoride transfer (cEFT) mechanism, we wish to encourage the adoption of a systematic framework for the analysis of radical halogen reactivity, similar to that employed for PCET reactions.

PMID:日期:2026-09-25Enantiomeric protonated 2-amino-1-propanol (APH) chiral cations are introduced to partially substitute K sites in KTiF:Mn, triggering effective chirality transfer to Mn luminescent centers. The as-prepared chiral hybrid fluorides exhibit mirror-image circular dichroism and narrow-band red CPL originating from Mn 2E → A transitions, with a maximum || up to 2.0 × 10.

PMID:日期:2026-09-25A robust Cr-decorated Ni(OH)/NF electrocatalyst for efficient ethanol upcycling achieves 50 mA cm at 1.348 V RHE with >95% acetate selectivity and 100 h stability. Raman spectroscopy reveals accelerated NiOOH formation, while DEMS indicates a preferential C2 oxidation pathway during ethanol electrooxidation. A Cr-decorated Ni(OH)/NF electrocatalyst efficiently upcycles ethanol to acetate with >95% selectivity and 100 h stability.

5. Cucurbituril-modulated NIR emission and two-photon mitochondrial imaging of an acridine derivative.
PMID:日期:2026-09-25Host-guest assemblies of an acridine dye with cucurbit[7]uril and cucurbit[8]uril give distinct NIR emissions at 674 and 708 nm, respectively. Both exhibit efficient two-photon absorption near 925 nm and successfully enable single- and two-photon mitochondrial imaging in live A549 cells.

6. Ionic organic molecular cage-supported Pd nanoparticles for aqueous Suzuki-Miyaura coupling.
PMID:日期:2026-09-25Spiroborate-linked organic molecular cages bearing bipyridine and phenanthroline ligands stabilize palladium nanoparticles whose dimensions are consistent with exocyclic growth. The cage-supported Pd nanoparticles act as efficient, recyclable catalysts for aqueous Suzuki-Miyaura coupling, affording high conversions under mild conditions while maintaining cage integrity, nanoparticle morphology, and activity over multiple cycles.

7. Total synthesis as a critical tool for structural revision of natural products.
PMID:日期:2026-09-25Structural misassignments of natural products remain an important challenge despite significant advances in spectroscopic, chiroptical, and computational methods, owing to factors such as conformational flexibility, limited availability of natural isolates, and stereochemical ambiguity. Total synthesis provides a powerful approach for evaluating and revising proposed structures through direct comparison of spectroscopic, crystallographic, and chiroptical data of synthetic compounds with those of the corresponding natural isolates. This review highlights representative case studies of natural product structural revisions established through total synthesis between 2020 and 2025, including contributions from our laboratory. These examples illustrate the role of total synthesis in resolving structural ambiguities through stereochemical revisions, biosynthesis-guided structural revisions, and complementary computational analyses. Collectively, these studies demonstrate that total synthesis remains an important tool for structural verification and revision, providing a robust foundation for advances in natural product chemistry, biosynthetic studies, and drug discovery.

PMID:日期:2026-09-25Herein, we established diacetyl as a platform reagent for diversity-oriented aldehyde C(sp)-H functionalisation, which was enabled by the efficient generation of acyl radicals visible-light-induced hydrogen atom abstraction. This fundamental reactivity was seamlessly integrated into unified C(O)-X bond-forming processes, delivering structurally diverse and value-added carbonyl derivatives.
