文摘In this work,we synthesize two luminescent Pt(Ⅱ)complexes using differentπ-conjugated bidentate ligands.Both complexes are assembled into three-dimensional(3D)networks through non-classical intermolecular interactions in the crystal state.Unexpectedly,substituting pyridine with the more extensivelyπ-conjugated quinoline significantly increases the dihedral angles between the phenyl and quinolyl groups of the bidentate ligands.This alteration disrupts theπ-πinteractions between molecules,resulting in distinct optical properties upon exposure to external stimuli.By integrating these complexes into polymers,we fabricate electrospun films containing luminescent nanofibers that exhibit reversible optical changes.These findings have paved the way for the development of high-performance optical encryption and anti-counterfeiting materials,achieved through the employment of simple chromophores.

文摘Supramolecular materials,characterized by dynamic reversibility and responsiveness to environmental stimuli,have found widespread applications in numerous fields.Unlike traditional materials,supramolecular materials that rely on non-covalent interactions can allow spontaneous reorganization and self-healing at room temperature.However,these materials typically exhibit low strength due to the weak bonding energies of non-covalent interactions.This study presents the development of a high-strength self-healing supramolecular material that combines multiple interactions including ionic bonding,hydrogen bonding,and coordination bonding.The material,formed by the aggregation of the negatively charged picolinate-grafted copolymer(PCM)with positively charged hyperbranched molecules(HP),is further enhanced by Eu^(3+)ion complexation.The resulting film exhibits a high modulus of 427 MPa,tensile strength of 10.5 MPa,and toughness of 14.7 MJ m^(−3).Meanwhile,the non-covalent interaction of this supramolecular material endows it with a self-healing efficiency of 92%within 24 h at room temperature,as well as multiple remolding properties.The incorporation of lanthanide ions also imparts tunable fluorescence.This study not only provides insights into the development of high-strength self-healing materials but also offers new possibilities for the functionalization of supramolecular materials.

文摘Although manganese-based oxide is regarded as a promising cathode material for zincion hybrid supercapacitors(ZHSCs),its practical application is hindered by slow zinc ion diffusion and the instability of MnO_(2).To overcome this obstacle,a δ-MnO_(2)/MXene heterostructure was created using a simple one-step process under gentle condition.The ZHSC was assembled using this heterostructure as the cathode,activated carbon(AC)as the anode and 2 mol·L−1 ZnSO_(4) as the electrolyte.The resultingδ-MnO_(2)/MXene//ZnSO4//AC ZHSC shows a maximum specific capacitance of 97.4 F·g^(−1) and an energy density of 32.27 Wh·kg^(−1) at the best cathode-to-anode mass ratio.Ex situ characterizations reveal the reversible energy storage mechanism combing Zn^(2+)insertion/extraction in the cathode,ion adsorption and desorption on the anode surface,and partial reversible formation and dissolution of Zn_(4)SO_(4)(OH)_(6)·5H_(2)O(ZHS)components on both electrodes.Adding of Mn^(2+)to the electrolyte reduced Mn dissolution,improving the ZHSC’s specific capacitance and energy density to 140.4 F·g^(−1) and 49.36 Wh·kg^(−1),respectively,while also enhancing its rate performance and cyclability.The improved electrochemical reaction kinetics was verified through various tests.The results suggest that the δ-MnO_(2)/MXene heterostructure has great potential as a high-performance cathode material for ZHSCs.

文摘The aqueous preparation of Na_(3)(VOPO_(4))_(2)F cathode material with low cost and good structural stability has attracted extensive attention for advancing sodium-ion batteries(SIBs).However,the inclusive heterogeneous cations incorporated into the material lattice,dominated by coordination chemistry,are always overlooked.Herein,the embroiled NH_(4)^(+)/H_(3)O^(+)cations in the Na_(3)(VOPO_(4))_(2)F lattice have been first disclosed during aqueous co-precipitation.It involves the electrostatic interactions between hydrogen protons(NH_(4)^(+)/H_(3)O^(+))and electronegative oxygen atoms(V=O and V–O–P groups),which induces the terrible Na^(+)-storage performance,as demonstrated by multiple characterizations.Followingly,the very-facile operation,i.e.heat treatment,has been raised to remove NH_(4)^(+)/H_(3)O^(+)cations and then achieved high-performance Na_(3)(VOPO_(4))_(2)F.Therefore,the Na_(3)(VOPO_(4))_(2)F||Na cell contributes to the significantly improved discharge capacity(129.7 mAh g^(−1))and voltage plateau from 3.63 to 3.87 V(vs.Na/Na^(+))at 0.2 C.The ultrahigh capacity retentions of 93.7%and 76.7%after 1000 and 3500 cycles at 1 and 20 C rates under 25°C are harvested,respectively,as well as high/low-temperature performances and rate capability.Eventually,the as-assembled Na_(3)(VOPO_(4))_(2)F||hard carbon full-cell delivers excellent long-term cycling stability over 1000 cycles with 97.5%retention at 3 C.These emphasize the high-efficacy synthesis of Na_(3)(VOPO_(4))_(2)F and provide insights into the aqueous co-precipitation for the development of materials used in SIBs.

文摘Lithium metal is one of the most promising anodes for lithium batteries because of their high theoretical specific capacity and the low electrochemical potential.However,the commercialization of lithium metal anodes(LMAs)is facing significant obstacles,such as uncontrolled lithium dendrite growth and unstable solid electrolyte interface,leading to inferior Coulombic efficiency,unsatisfactory cycling stability and even serious safety issues.Introducing low-cost natural clay-based materials(NCBMs)in LMAs is deemed as one of the most effective methods to solve aforementioned issues.These NCBMs have received considerable attention for stabilizing LMAs due to their unique structure,large specific surface areas,abundant surface groups,high mechanical strength,excellent thermal stability,and environmental friendliness.Considering the rapidly growing research enthusiasm for this topic in the last several years,here,we review the recent progress on the application of NCBMs in stable and dendrite-free LMAs.The different structures and modification methods of natural clays are first summarized.In addition,the relationship between their modification methods and nano/microstructures,as well as their impact on the electrochemical properties of LMAs are systematically discussed.Finally,the current challenges and opportunities for application of NCBMs in stable LMAs are also proposed to facilitate their further development.

文摘The functional properties of glasses are governed by their formation history and the complex relaxation processes they undergo.However,under extreme conditions,glass behaviors are still elusive.In this study,we employ simulations with varied protocols to evaluate the effectiveness of different descriptors in predicting mechanical properties across both low-and high-pressure regimes.Our findings demonstrate that conventional structural and configurational descriptors fail to correlate with the mechanical response following pressure release,whereas the activation energy descriptor exhibits robust linearity with shear modulus after correcting for pressure effects.Notably,the soft mode parameter emerges as an ideal and computationally efficient alternative for capturing this mechanical behavior.These findings provide critical insights into the influence of pressure on glassy properties,integrating the distinct features of compressed glasses into a unified theoretical framework.
