Herein, extrinsic pseudocapacitive (PDC) cathode materials with different carbon contents were synthesized using FeSO4·7H2O waste through a simple ball milling and annealing process, which enhances sodium storage kinetics and achieves waste recycling. The results indicate that NFSO particles and graphite flakes create a disordered porous structure, which enhances the PDC effect, thus overcoming the slow migration rate of sodium-ions. Specifically, the diffusion coefficient of NFSO/C-10 increased by around an order of magnitude compared to that of NFSO, increasing from 10−12 to 10−11. The discharge capacity reached 84 mA h g−1 at 0.2C (1C = 91 mA g−1). The present work realizes the high-value reuse of waste and highlights the crucial role of the PDC effect in enhancing diffusion dynamics, which opens up a new direction for the design and synthesis of high-rate iron-based sulfate cathode materials.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 6","pages":" 1043-1052"},"PeriodicalIF":6.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, recent research has revealed an intriguing counterpoint termed as “anti-heavy-atom effect”. The introduction of halogens into aggregation-induced emission (AIE) luminescent materials leads to enhanced fluorescence emission. Herein, we synthesized a series of (ethene-1,1,2,2-tetrayltetrakis(benzene-4,1-diyl))tetrakis (phenylmethanone) (ETTP) derivatives with different positions of bromine substitutions to explore their structural-photophysical relationships. Contrary to our expectations, the brominated ETTP derivatives did not exhibit a higher fluorescence quantum yield (ΦF) than ETTP. Single-crystal analysis and theoretical calculations revealed that the absence of bromine-based bonding resulted in inadequate suppression of non-radiative relaxation pathways. Moreover, the introduction of carbonyl groups, with their lone electron pairs, resulted in interactions with the excited-state electrons, leading to a decrease in fluorescence intensity. Furthermore, the ETTP derivatives displayed excellent mechanofluorochromic properties arising from crystalline-to-amorphous phase transformations, which could have potential applications in information storage and anti-counterfeiting. This study demonstrates that if the introduced halogen atoms in AIE materials do not participate in the bond formation, the fluorescence emission will not be enhanced. These findings provide deeper insights into traditional views and hold significant implications for future developments of novel high-efficiency AIE-active materials.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 8","pages":" 1228-1239"},"PeriodicalIF":6.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the design of excellent porphyrin or phthalocyanine NLO materials with both strong second and third NLO properties remains challenging. In the present work, the merger of azulene-based graphene (azugraphene) nanosheets with porphyrin (phthalocyanine) brings about hybrid structures with strong NLO responses and good chemical stability through polarizing the enhanced π-conjugation. Among these designed molecules, the azugraphene merged porphyrin PN-3A-A has the largest static first hyperpolarizability per heavy atom (〈β0〉/N of 449.99 × 10−30 esu) and second hyperpolarizability per heavy atom (〈γ0〉/N of −11.28 × 10−34 esu). The addition of Mg into PN-3A-A further enhances the second and third order NLO properties, and the 〈β0〉/N and 〈γ0〉/N values of Mg-PN-3A-A reach 454.07 × 10−30 esu and −11.37 × 10−34 esu, respectively. The strong third order NLO responses of the porphyrin and metalloporphyrin derivatives in the near-infrared region confer these molecules potential applications in optoelectronics and biomedical engineering owing to the extended π-conjugation of the N-doped polar graphene nanosheets and the biocompatibility of porphyrin. This work provides useful information for designing multi-functional materials by properly combining the merits of functional components.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 7","pages":" 1149-1165"},"PeriodicalIF":6.0,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fused-ring electron acceptors (FREAs), as NIR dyes, hold great potential in optical limiting due to their strong electron mobilities. In this study, optical nonlinearities of FREAs (IEICO-4F and ITIC-4F) are investigated within the NIR window (850–1550 nm). Under the combined contributions of two-photon absorption (TPA), TPA-induced excited state absorption or three-photon absorption (3PA), both compounds exhibit broadband reverse saturation absorption, which extends to 1550 nm. Especially for IEICO-4F, its TPA cross-section reaches 26 700 GM at 950 nm under 190 fs and it has an ultralow optical limiting threshold (0.44 mJ cm−2). In comparison with ITIC-4F, increasing the conjugated length in IEICO-4F by non-covalent interaction between ‘O’ and ‘S’ atoms effectively modulates its molecular band gap and remarkably enhances its optical nonlinear response. Additionally, the nonlinear refraction of FREAs displays obvious self-defocusing in the near-resonance region, which is primarily governed by a bound electron response (Kerr effect). Our results indicate that FREAs with electron-rich cores are greatly promising as optical limiting materials and warrant further exploration in nonlinear optics.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 6","pages":" 1020-1030"},"PeriodicalIF":6.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we prepared a novel chitosan-based green active composite film, employing chitosan nanoparticles encapsulating gallic acid as nanofillers. The interfacial interactions between the nanoparticles and chitosan matrix were found to significantly enhance the mechanical properties and barrier properties of the composite film. Moreover, the integration of gallic acid-loaded nanoparticles substantially improved the antimicrobial and antioxidant activities of the composite film. These improvements are crucial for inhibiting the proliferation of food-borne microorganisms and the oxidation of lipids, thereby preserving the quality and safety of foods. Freshness preservation experiments have demonstrated that this composite film could effectively mitigate the quality degradation of crayfish meat during storage, thereby verifying its potential application in the field of food packaging. Consequently, this sustainable bio-based green active packaging film has the potential to replace the traditional petroleum-based packaging film and inspires the development of new sustainable bio-based active packaging films.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 6","pages":" 1053-1065"},"PeriodicalIF":6.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two-photon PDT has garnered significant interest in the biomedical field for its ability to activate photosensitizers by simultaneously absorbing two near-infrared (NIR) photons. Distinguished from one-photon excited PDT, two-photon excited PDT (TPE-PDT) utilizes two NIR photons for excitation, offering increased tissue penetration, improved spatial resolution, reduced background fluorescence, and decreased photodamage and photobleaching. These advantages make it highly beneficial for tumor treatment. Developing novel TPE-PDT strategies that feature long emission wavelengths, robust light stability, and subcellular organelle targeting is challenging. This study introduces a mitochondrial targeting TPE-PDT scheme based on aggregation-induced emission properties. The nanoparticles demonstrated highly specific mitochondrial targeting. These nanoparticles efficiently generated reactive oxygen species upon exposure to an 830-nm femtosecond laser. This activates the GSDME pyroptosis pathway, leading to effective tumor cell eradication. Hence, this study presents an innovative therapy approach that significantly enhances the efficacy of PDT, making it a possible contender for cancer therapy in translational nanomedicine.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 8","pages":" 1267-1277"},"PeriodicalIF":6.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This challenge has sparked tremendous interest among scientists, driving the pursuit of innovative methods to vitrify non-meltable ZIFs for various applications. Herein, we show a universal approach for synthesizing glasses and foams from non-meltable and porous ZIFs, such as 2D ZIF-7 and 3D ZIF-8, which stand as the most promising porous materials of the ZIF family. This approach is based on the combination of liquid-mediated sequential structure perturbation and post-heat treatment, yielding a variety of highly microporous ZIF foams like glass. The synthesized ZIF foams exhibit superior gas adsorption capacities compared to melt-quenched ones. The as-fabricated membranes based on ZIF foams demonstrate ultrahigh H2 permeance and good H2/CH4 selectivity. In comparison to the melt-quenching technique, our structural perturbation strategy allows for the synthesis of a significantly greater quantity of glasses and foams from a single batch. It greatly broadens the composition range of ZIFs for glass and foam formation. Consequently, this study holds significant potential for upscaling the synthesis of microporous ZIF foams like glass to address a diverse array of applications such as energy storage, gas sorption and separation.
