Abstract Zero‐dimensional (0D) metal halides have drawn increasing attention due to the attractive structure dependent photoluminescence (PL) properties. Here, we report two new 0D organic–inorganic hybrid Sb‐based halides, (MTP) 6 SbBr Sb 2 Br 9 ⋅H O (MTP=Methyltriphenylphosphonium, crystal 1) and 5 (crystal 2), featuring a reversible structural phase transformation tunable orange red emissions upon dehydration rehydration of H molecules. Intriguingly, subsequent heat treatment further...
Chiral hybrid organic-inorganic metal halides (HOMHs) with intrinsic noncentrosymmetry have shown great promise for applications in second-order nonlinear optics (NLO). However, established chiral HOMHs often suffer from their relatively small band gaps, which lead to negative impacts on transparent window and laser-induced damage thresholds (LDT). Here, we synthesized two based CuI halides, namely (R-/S-MBA)CuBr2 , feature well-balanced NLO performances a highly efficient SHG response,...

The two-dimensional (2D) perovskites have drawn intensive attention due to their unique stability and outstanding optoelectronic properties. However, the debate surrounding spatial phase distribution band alignment among different 2D phases in quasi-2D perovskite has created complexities understanding carrier dynamics, hindering material device development. In this study, we employed highly sensitive transient absorption spectroscopy investigate dynamics of (BA)2(MA)n−1PbnI3n+1...
X-ray detection is widely used in medical imaging, safety inspection, scientific research, and so on, which the Cs3Bi2I9 perovskite single crystal (SC) material has attracted increasing attentions for its excellent intrinsic properties (high absorption coefficient, low toxicity, high resistivity, etc.). However, existing methods this SC growth enable quality preparation cost, thus resulted defects of limit sensitivity, detectable dose rate, large-scale application Cs3Bi2I9-based device. In...
Understanding the nature of photogenerated carriers and their subsequent dynamics in semiconducting perovskites is important for development solar cell materials devices. However, most ultrafast dynamic measurements on perovskite were conducted under high carrier densities, which likely obscures genuine low densities illumination conditions. In this study, we presented a detailed experimental study density-dependent hybrid lead iodide from femtosecond to microsecond using highly sensitive...
A versatile Rh(<sc>i</sc>)-catalyzed C6-selective decarbonylative C–H alkenylation of 2-pyridones with readily available alkenyl carboxylic acids has been developed.
A Rh-catalyzed chelation-assisted C6-selective C-H activation/alkylation of 2-pyridones with readily available alkyl carboxylic acids or anhydrides is introduced. The reaction proceeds via substrate decarbonylation. This approach merges functionalization anhydrides, allowing for the efficient synthesis various C6-alkylated good functional group tolerance.
Transition metal sulfides (TMSs) are widely recognized for their potential as anode materials in the development of flexible lithium-ion capacitors (FLICs) owing to high theoretical capacity. However, practical application has been significantly limited by rapid capacity decay and sluggish kinetics associated with TMS volume variation. In response these challenges, we have prepared ZnS/CuS nanoparticles embedded continuous multichannel carbon fibers (CFs). This was achieved through a process...
Abstract Accurate structure control in dissipative assemblies (DSAs) is vital for precise biological functions. However, accuracy and functionality of artificial DSAs are far from this objective. Herein, a novel approach introduced by harnessing complex chemical reaction networks rooted coordination chemistry to create atomically‐precise copper nanoclusters (CuNCs), specifically Cu 11 (µ 9 ‐Cl)(µ 3 ‐Cl) L 6 Cl (L = 4‐methyl‐piperazine‐1‐carbodithioate). Cu(I)–ligand ratio change dynamic...
Dozens of extracellular molecules jointly impact a given neuron, yet we lack methods to simultaneously record many such signals in real time.

The identity detection sensitivity each cell determined via robotic...
Convective weather, often associated with heavy precipitation, hail, lightning, and other hazardous phenomena, is highly unpredictable, short-lived, localized, making forecasting early warning particularly challenging. The formation of lightning closely tied to the thermodynamic microphysical processes within severe convective weather systems (e.g., Qie et al., 2021). Not only does it pose a significant threat human life properties, but has also been recognized by International...

Abstract 2D Ruddlesden–Popper (RP) layered metal‐halide perovskites have garnered significant interest due to their unique photoelectric properties and excellent stability. However, perovskite films prepared via solution process generally exhibit multi‐quantum well structure with random width distribution, which significantly impedes the carrier transportation. Herein, synthesis of phase‐pure (PEA) 2 FAPb I 7 (PEA = C 8 H 11 N, FA CH 4 N ) thin is reported in ambient environment achieved by...
