The resulting supramolecular polymer, 10BrP5-TPPA (10BPTP for short), shows exceptional iodine capture capabilities, removing volatile iodine at a rate of 1.57 g g–1 h–1 and rapidly capturing iodine from solution with a kinetic rate of 2.7 × 10–2 g mg–1 min–1. This approach leverages the unique properties of halogen bonding to construct a stable and functional material for efficient iodine adsorption, offering valuable insights for the future development of iodine adsorbents.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1905–1913 1905–1913"},"PeriodicalIF":9.6,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903186","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}

IDBmPPC with a single bond in a seven-membered nitrogen-containing heterocycle obtains a ΔEST of 0.03 eV, a reverse intersystem crossing rate of 2.85 × 106 s–1, and a horizontal dipole orientation (Θ//) of 85% in the solid state.

Cross-linked poly(3-vinyl-N-methylphenothiazine) (X-PVMPT) is a p-type OAM showing high performance and enabling fast and reversible energy storage in different battery configurations. Beyond its molecular or polymer structure, the performance of an OAM depends strongly on the structure of the composite electrode. The porous nanostructure of an electrode composed of X-PVMPT, a conductive carbon additive, and binder is statistically investigated based on highly resolved 3D image data. Univariate probability distributions of relevant morphological descriptors and bivariate distributions of pairs of such descriptors are parametrically modeled. In this way, local heterogeneities and spatial gradients are quantified.

Here, we demonstrate the tunable mechanical performance of aluminum oxyhydroxides as cementitious materials through an alkali-controlled dehydroxylation reaction pathway for long-term applications under supercritical geothermal environments. Notably, the synthesized aluminum oxyhydroxides demonstrate remarkable stability, maintaining superior mechanical performance under supercritical conditions for over 30 days. Synchrotron X-ray diffraction, spectroscopy measurements and geochemical thermodynamic modeling uncover that the gibbsite dehydroxylation pathway functions as a key dial for tuning the chemomechanics, rendering the aluminum oxyhydroxide a strong cementitious material. By uncovering the mechanistic role of alkali-driven dehydroxylation, this work proposes a cementitious chemistry distinct from conventional Portland cement and geopolymer-dominated alkali-activated systems, laying the groundwork for developing next-generation cementitious materials for supercritical geothermal energy exploitation.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1869–1878 1869–1878"},"PeriodicalIF":9.6,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903185","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}

However, the fabrication of organic polymer films with these two tunable photoresponsive characteristics remains a challenge. Herein, an organic photochromic phosphor, 2,2’-dinaphthylamine, is described, and hybrid polymer films with tunable RTP and photochromism characteristics were prepared by simply doping the chromophore into different functional polymer matrices of PS, PMMA, and PAN at a low mass fraction of 1%. As the polarity of side chains increases, the electrostatic interactions between the chromophore and polymer matrices increase accordingly, leading to the enhanced RTP and declined photochromism. The transition mode of excited-state energy for RTP or photochromism could be regulated by simply altering functional polymer matrices, providing valuable information for understanding the inherent mechanism. Furthermore, multilevel advanced encryption and information storage systems based on hybrid polymer materials are manufactured.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1860–1868 1860–1868"},"PeriodicalIF":9.6,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903182","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}

Here, we report two-dimensional (2D) β-CuI monolayers prepared from γ-CuI via phase transformation and liquid-phase exfoliation. These monolayers stably exist under ambient conditions and have a hexagonal structure with a lateral size of ∼500 nm and thickness of 1 nm. Theoretical calculations indicate that the preparation of 2D β-CuI monolayers arises from low exfoliation energy along with dynamic and thermodynamic stability. Interestingly, the 2D β-CuI exhibits a unique self-trapped exciton luminescence phenomenon, emitting a broad white light spectrum close to full-spectrum illumination of sunlight. The findings represent a step toward the preparation of 2D β-CuI under ambient conditions and pave the way for the exploration of its unique properties and applications.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1845–1851 1845–1851"},"PeriodicalIF":9.6,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903179","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}

Here, we use current-sensing atomic force microscopy (CS-AFM) to probe the Li+ migration and nanomechanical properties in SPEs with varying salt loadings. Topological and ionic current mapping over 80 × 80 μm2 under 0.5 V bias reveals that LiClO4 induces rapid spherulitic growth, expelling salt and causing spatial heterogeneity in conductivity. In contrast, LiTFSI yields more homogeneous structures and conduction. Elemental and nanomechanical mapping confirms these patterns, showing distinct moduli and hardness between crystalline and amorphous regions in LiClO4-based SPEs, while LiTFSI-based systems remain more uniform. These spatial variations adversely affect electrode contact and long-term stability.
