These iCOFs are characterized by numerous hydrophilic sites and high water stability, enabling efficient water vapor adsorption even at relatively low humidity levels. Through the use of various hygroscopic salt cations and precise control of ion concentration within the pores, the water state within the iCOFs pores can be effectively managed. Among the iCOFs, TB-COF-Li stands out with an impressive adsorption capacity of 0.24 g g-1 from 0 to 22% RH. Notably, due to its ionic porous structure, TB-COF-Li exhibits a significantly lower enthalpy of evaporation, measured at 967.04 J g-1, compared to bulk water with an enthalpy of 2387.4 J g-1. Moreover, under simulated conditions of 1.5 solar intensity at 60 °C, the majority of the adsorbed water can be rapidly desorbed without the need for additional energy input. This efficient desorption process contributes to a high water collection rate of 0.092 g g-1 h-1 in the final atmospheric water harvesting device. The development of these iCOFs offers a promising and cost-effective solution for obtaining fresh water in arid regions.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"25 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832714","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}

Rechargeable calcium batteries are such an emerging technology, which shows the potential to provide high cell voltage and high energy density close to lithium‐ion batteries. Additionally, the use of Ca2+ as a charge carrier renders significant sustainable values. Although pioneering work on the electrochemistry of Ca has been carried out for more than half a century, demonstration of reversible Ca chemistries in non‐aqueous media was only achieved within the past decade. In this review, we will present recent development of rechargeable calcium batteries, focusing on mainly the similarities but also differences between Ca chemistry and other post‐lithium chemistry. According to the periodic nature of elements, magnesium (an alkaline earth element as Ca) and sodium (a diagonally adjacent element to Ca) have similar chemical properties to Ca in various aspects. We shall elaborate on how the solution chemistry, metal behaviors and transport mechanisms of Ca can be better understood in light of the established principles in the respective Mg/Na systems.

The innovative design and synthesis of inhibitors to target drug-resistance-specific proteins is highly desirable. However, challenges remain in precisely adjusting their conformation and stereochemistry to adapt the chiral regions of target proteins. Herein, using a stepwise programmable modular assembly approach, we precisely engineered two pairs of homochiral dinuclear Ir(III) metallohelices (Λ2S4-Hbpy and Δ2R4-Hbpy, Δ2S4-Hbpy and Λ2R4-Hbpy) functionalized with flexible dithiourea linkages. The resulting homochiral metallohelices exhibited significant chirality-dependent photocytotoxicities, and the enhanced structural compatibility ofΔ2S4-Hbpywith the target cyclin-dependent kinase 1 (CDK1) contributed to its superior photodynamic therapy efficacy, achieving an outstanding photocytotoxicity index (PI) value of 2.3×104. Interestingly, emerging as a critical mediator in the development of oxaliplatin resistance, CDK1 targeting by Δ2S4-Hbpyachieved enhanced cellular uptake, anticancer activity, and oncosis-mediated cell death in oxaliplatin-resistant HCT8/L cells. Mechanistic investigations, including proteomic profiling and CDK1 gene silencing, confirmed the pivotal role of chirality-selective CDK1 targeting in reversing metallodrug resistance.

This study investigates the heptapeptide Ac-IHIHIQI-NH2 and its intrinsic fluorescence across a range of pH levels, demonstrating that variations in pH lead to significant changes in the morphology of the self-assembled structures. While the position of the fluorescence emission remains constant—due to the stability provided by the hydrogen bonding network of the peptide backbone—the intensity of the fluorescence exhibits a direct correlation with the degree of self-assembly. This finding underscores a dynamic relationship between structural morphology and optical properties. Notably, the ability of the peptide to self-assemble under diverse pH conditions is a novel observation that contrasts with previously reported literature. By employing a computationally driven approach, complemented by rigorous experimental validation, this work establishes a new paradigm for studying complex interacting systems such as peptide self-assembly. Our findings enhance the understanding of how environmental factors influence peptide behavior and pave the way for the design of innovative peptide-based materials with tunable optical characteristics, with potential applications in bioluminescent probes and diagnostic tools for neurodegenerative diseases.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"7 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816441","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, limited structural diversity of spiro frameworks significantly restricts the expansion of their applications. Here we present a new class of axially chiral spiro-bisindole frameworks and report their first enantioselective construction via a chiral phosphoric acid-catalyzed intramolecular dehydrative cyclization reaction. Unlike the classical SPINOL backbone, incorporation of indole moieties in place of phenol enhances the nucleophilicity of ketone substrates, thereby eliminating the need for a tedious pre-activation process. By leveraging the retained active sites of indole, the resulting highly enantioenriched spiro-bisindoles can be rapidly transformed into other valuable structures. More importantly, axially chiral fluorescent molecules with good asymmetry factors and quantum fluorescence efficiency are readily accessed, opening a new avenue for developing chiral fluorescent materials. Control experiments demonstrate the pivotal role of both unmasked N-H bonds in achieving good efficiency and enantiocontrol.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"6 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820978","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}

Rational control over these processes and insights into the mechanisms are crucial to improve synthetic methodology and achieve COF films with regular channels. Here, we report the controllable synthesis of COF films via the temperature-swing strategy and explore their crystallization from monomer assemblies to film formation. A detailed time-dependent study reveals that COF crystallites preferentially coalesce at low temperature, progressing from assembled nanospheres to continuous films through lateral and vertical interactions. Moreover, appropriately elevating the synthesis temperature promotes crystal growth and eliminate the defects of weakly crystalline regions, contributing to highly crystalline and porous COF film with a surface area of 746 m2 g−1. The prepared COF composite membrane exhibits a methanol permeance of 97.8 L m-2 h-1 bar-1, which is five times higher than the weakly crystalline counterpart. In addition, the molecular sieving test recognize great membrane selectivity to discriminate the antibiotic mixture with a high separation factor of 15.4.

We ascribe the high performance and stability to the site-selective, stable coordination of Pt within the C3N4 structure.
