Here, switchable colossal anisotropic thermal expansion (ATE) behaviors are realized in a Hofmann-type framework [Fe(bpy-NH2){Au(CN)2}2]·iPrOH (Fe·iPrOH, bpy-NH2 = [4,4'-Bipyridin]-3-amine) through a three-in-one strategy: vibrational mechanism, electronic mechanism and molecular motion. Spin crossover (SCO) centers coordinate with dicyanoaurate linkers to form flexible wine-rack frameworks, which exhibits structural deformations driven by host-guest interactions with iPrOH molecules. By means of vibrational mechanism, a scissor-like motion driven by the rotation of dicyanoaurate is observed within the rhombic grids, resulting in the emergence of colossal ATE in the high temperature region. When spin transition comes into play, electronic mechanism is predominant to form reverse ATE behavior, which is associated with host-guest cooperation involving significant molecular motion of iPrOH guest and adaptive deformation of host clathrate. A remarkably high negative thermal expansion coefficient up to −7.49×105 MK−1 accompanied with abrupt SCO behavior is observed. As a proof of concept, this study opens a novel perspective for designing dynamic crystal materials with tunable thermomechanical property by integrating various ATE-related elements into a unified platform.","PeriodicalId":9909,"journal":{"name":"Chemical Science","volume":"36 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143797707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such catalysts are typically operative through the classical redox mediated mechanism, where dynamic equilibriums of Co2+/3+ and Co3+/4+ redox are present before and throughout the OER cycle. The generation of low-valent Co2+ sites is however disadvantageous for proceeding the catalysis. To this end, sulfate groups embedded in graphene were developed to link a model Co-2, 2'-bipyridine complex toward synthesis of a novel Co based HMC, generating a specific CoN2O4S1 coordination moiety. Such molecular Co sites were induced to convert from +2 to +3 oxidation state at the open circuit condition through their proton coupled electron transfer nature. This process ultimately eliminated the generation of Co2+ state from its redox equilibrium, and efficiently improved the turnover frequencies of Co sites toward OER with two-order dependence on the concentrations of OH− ions. This work provides a novel mechanistic perspective for the rational design of high-performance HMCs.","PeriodicalId":9909,"journal":{"name":"Chemical Science","volume":"18 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143797678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, the EF-driven dative bond is demonstrated through the study of interactions between PH3 and curved carbon-based nanostructures. The P→C dative bonds emerge only in the presence of EFs, whereas the interactions in the absence of EFs lead to van der Waals (vdW) complexes. The formation of EF-driven dative bonds can be verified with distinctive signals in vibrational, carbon-13 NMR, and UV/Vis spectra. The nature of EF-driven dative bonds was theoretically analyzed with the block-localized wavefunction (BLW) method and its associated energy decomposition (BLW-ED) approach. It was found that the charge transfer interaction plays a dominating role and that even in the presence of EFs, complexes dissociate to monomers once the charge transfer interaction is “turned off”. Notably, the inter-fragment orbital mixing stabilizes the complexes and alters their multipoles, leading to additional stability through field-multipole interactions. This conclusion was supported by further decomposition of the charge transfer energy component, clarifying the precise role of orbital mixing. The inter-fragment orbital mixing, which occurs exclusively in the presence of EFs, was elucidated using “in-situ” orbital correlation diagrams. Specifically, both external EFs and intermolecular perturbations remarkably reduce the energy gap between the frontier orbitals of the monomers, thereby facilitating inter-fragment orbital interactions. Significant covalency was confirmed through ab initio valence bond (VB) theory calculations of the EF-driven dative bonds, aligning with the crucial role of the charge transfer interaction. This pronounced covalency emerges as a key feature of EF-driven interactions, setting them apart from traditional dative bonds studied in parallel throughout this work.","PeriodicalId":9909,"journal":{"name":"Chemical Science","volume":"35 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143797679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This combination of data depth and quantity creates the opportunity to unite advanced data science approaches, such as Machine Learning (ML), with 2D-IR to reveal insights that surpass those from established data interpretation methods. To demonstrate this, we show that ML and 2D-IR spectroscopy can classify blood serum samples collected from patients with melanoma according to diagnostically-relevant groupings. Using just 20 μL samples, 2D-IR measures ‘protein amide I fingerprints’, which reflect the protein profile of blood serum. A hyphenated Partial Least Squares-Support Vector Machine (PLS-SVM) model was able to classify 2D-protein fingerprints taken from 40 patients with melanoma according to the presence, absence or later development of metastatic disease. Area under the receiver operating characteristic curve (AUROC) values of 0.75 and 0.86 were obtained when identifying samples from patients who were radiologically cancer free and with metastatic disease respectively. The model was also able to classify (AUROC = 0.80) samples from a third group of patients who were radiologically cancer-free at the point of testing but would go on to develop metastatic disease within five years. This ability to identify post-treatment patients at higher risk of relapse from a spectroscopic measurement of biofluid protein content shows the potential for hybrid 2D-IR-ML analyses and raises the prospect of a new route to an optical blood-based test capable of risk stratification for melanoma patients.","PeriodicalId":9909,"journal":{"name":"Chemical Science","volume":"59 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143813700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the production process of layered oxides, another popular cathode material for SIBs, requires prolonged high-temperature sintering, resulting in significant energy consumption. To address the aforementioned issues, a \"two birds with one stone\" strategy is proposed. This approach not only demonstrates the feasibility of directly preparing layered oxides with PBAs as precursors through a fast sintering process but also simultaneously addresses the challenge of treating unqualified PBAs while minimizing excessive energy consumption during the preparation of layered oxides. Furthermore, a series of binary, ternary, and quaternary layered oxides were synthesized directly by utilizing PBAs with varying compositions, showcasing the universality of this strategy. This innovative approach breaks the boundaries between different types of sodium cathode materials and builds a distinctive bridge for the direct conversion of PBAs into layered oxides, thereby widening the feasibility of the cathode for SIBs.","PeriodicalId":9909,"journal":{"name":"Chemical Science","volume":"23 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143782938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some bismuth-based materials have been applied to storage Zn2+ or NH4+, indicating that one bismuth-based compound may be innovatively used in both zinc-ion and ammonium-ion batteries (ZIBs and AIBs). Herein, we successfully design a poly(3,4-ethylenedioxythiophene) (PEDOT) coated and embedded Bi2Te3 (Bi2Te3@PEDOT). Theoretical calculations and experimental researches demonstrate that the PEDOT coating and its intercalation into the interlayer enhance the structural stability of Bi2Te3 and significantly improve the storage capacities for Zn2+ and NH4+. The PEDOT intercalation results in an increased interlayer spacing and a charge redistribution in the interlayer, facilitating the charge transfer.

Herein, halide perovskites of Cs2SnX6 (X = Cl, Br, I) with varying halide anions are purposefully designed to unveil the halogen-induced regulatory mechanism. Theoretical calculations demonstrate that increasing the halogen atomic number induces the shift of p-band center closer to the Fermi level, which results in the localized charge distribution around halide anions, and rapid charge separation/transfer at Sn sites, enhancing the adsorptive-catalytic activity and redox kinetics of LiPSs. Experimental investigations exhibit that LSBs assembled with the Cs2SnI6 modified separator deliver a high initial capacity of 1000 mAh g‒1 at 2 C, with a minimum decay rate of 0.068% per cycle after 500 cycles. More impressively, the Cs2SnI6 battery with high sulfur loading (6.1 mg cm‒2) and low electrolyte/sulfur ratio (5.5 μL mg‒1) achieves a remarkable reversible capacity of 768.8 mAh g‒1, along with robust wide-temperature-tolerant cycling performance from −20 to 50 ºC.

To this end, we investigate here how electronic excitation redistributes spatially in a series of electron donor-acceptor (D-A) molecules containing two different donors, D and D', and organised in both linear D-A-D' and symmetric double-branch D'-A-D-A-D' geometries. Using transient IR absorption spectroscopy to probe the alkyne spacers, we show that for both types of systems in non-polar solvents, excitation remains delocalised over the whole molecule. In polar media, charge-transfer (CT) exciton in the linear D-A-D' systems localises rapidly at the end with the strongest donor. For the double-branch systems, excited-state symmetry breaking occurs and the CT exciton localises at the end of one of the two branches, even if the D' terminal donor is not the strongest one. This unexpected behaviour is explained by considering that the energy of a CT state depends not only on the electron donating and withdrawing properties of the donor and acceptor constituents, but also on the solvation energy. This study demonstrates the possibility to control the location of CT excitons in large conjugated systems by varying the nature of the donors and acceptors, the distance between them as well as the environment.","PeriodicalId":9909,"journal":{"name":"Chemical Science","volume":"108 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143775906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Synchrotron X-ray diffraction data of single crystals compressed with neon as the pressure-transmitting medium allowed the refinement of the crystal structure up to 28 GPa, at which the onset of the reaction was observed. Analysis of the pressure-dependent lattice parameters reveals a first-order isostructural phase transition at 13 GPa. We have solved the crystal structure of the high-pressure phase of azobenzene offering a key insight into the strong contribution of stress on the structural compression mechanism and crystal's reaction chemistry at elevated pressures. While the collapse of the b cell parameter, previously observed under non-hydrostatic conditions, was identified as the crucial step toward the formation of azobenzene-derived double-core nanothreads, under quasi-hydrostatic conditions the compression of the cell parameters up to 33 GPa followed a different route. The evolution of the cell's parameters and the refinement of the crystal structure close to the onset of the reaction identified a topochemical polymerization path, corroborated by reaction kinetics data by infrared spectroscopy and by computed polymer structures, suggesting a complex growth process, resulting in a distinctly different material compared to that formed upon non-hydrostatic compression.
