Water-soluble nanoparticles (NPs) based on the well-defined 4ThIID molecules, namely 4ThIID NPs, were prepared. Benefiting from the strong NIR-II absorption and high photothermal conversion properties of 4ThIID, the ε1064 × PTCE1064 value of 4ThIID NPs reaches 9.18 × 104, which is the highest value among the reported NIR-II photothermal small molecules. In vivo experiments show that 4ThIID NPs can effectively inhibit the growth of tumors in mouse models under the irradiation of a 1064 nm laser.

Controlling CsPbX₃ (X = Cl, Br, I) nanocrystal growth is challenging due to subsecond ionic metathesis. Here, spatial confinement at the hexane-acetonitrile interface enables precise kinetic control, achieving ultra-wide PL tunability (434-520 nm for CsPbBr₃, 541-662 nm for CsPbI₃) from blue-violet to green and yellow-green to deep red.

To date, SOFAST approaches have generally been limited to biomolecules. We present the applicability of SOFAST-HMQC techniques to small molecules in the slow-tumbling regime offering a time-efficient characterization of catalyst substrate hydrogen bonds with nitrogen at natural abundance. This extends NMR access to a broader range of catalyst substrate combinations.

Photoexcited nickel-catalyzed carbohalogenation reaction of fluoroalkenes has been demonstrated to afford halofluoroalkyl oxindoles featuring a quaternary center. The broad substrate scope with retention of fluorine atoms followed by efficient synthetic transformations of iodo-gem-difluoroalkyl oxindoles highlight the advantages of this methodology. Additionally, control experiments and DFT calculations have been conducted to illuminate the significance of the triplet-excited state of the nickel catalyst.

The impact of the electrode-electrolyte interface on the performance of zinc-metal batteries remains unclear. We propose a gradient SEI strategy, where the outer organic layer inhibits corrosion and the inner inorganic layer regulates Zn (002) crystal growth. This work offers new insights into the critical role of SEI layers.

Engineering optimal Si-based composites for Li-ion battery is significant. Here, we develop an iron sulfide (FeS) and carbon co-coated Si (Si@FeS/C) as high-performance anode. The Si@FeS/C structure reduces the formation of non-stable solid electrolyte interface, enabling good capacity and stability. The Si@FeS/C anode maintains 809 mAh g-1 at 0.1 A g-1 along with a Coulombic efficiency of 98% after 50 cycles, and displays a capacity of 669 mAh g-1 after 100 cycles at 0.2 A g-1. In addition, it displays a good stability at 50 °C. These findings provide a potential strategy for engineering coatings on Si to achieve high performances.
