Adsorption experiments demonstrate rapid, high-capacity removal of organic (methylene blue (MB), ≈30 wt%) and metallic (Pb + 2, ≈7 wt%) contaminants, outperforming commercial counterpart, with pseudosecond-order kinetics indicating chemisorption dominance. Competitive adsorption experiments reveal Pb selectivity, suppressing MB uptake while boosting Pb capacity (≈1.7-fold) which is attributed to lead–MB (Pb–MB) complexation.

The combination of high ionic conductivity, high-voltage stability, and lithium dendrite suppression has prompted the investigation of new solid-state electrolyte (SSE) systems. In this work, a SSE is reported based on a 4,4′-diamino-2,2′-stilbenedisulfonic acid constructed hydrogen-bonded organic framework (DS-HOF). The DS-HOF single crystal, leveraging its abundant hydrogen-bonding sites and polar groups, demonstrates an ionic conductivity of 1.65 mS cm<sup>−1</sup>, a lithium transference number of 0.42, and a wide electrochemical stability window of 5.5 V. The assembled lithium symmetric battery achieved stable cycling for over 1,300 h and uniform deposition, mainly due to the uniform transport of Li<sup>+</sup> through aligned Li<sup>+</sup> transport channels in DS-HOF and the buffering of structural changes during lithium deposition by flexible hydrogen-bonding networks. Furthermore, full cells assembled with LiFePO<sub>4</sub> cathodes retain 88% of their capacity after 200 cycles at 0.5 C, coupled with a high Coulombic efficiency of 99.92%. The electrolyte also demonstrates compatibility with a high-voltage NCM811 cathode, supporting stable cycling for 50 cycles without short-circuiting. These findings collectively underscore the significant potential of HOF-based materials as an emerging platform for next-generation SSEs.</p>","PeriodicalId":14686,"journal":{"name":"Israel Journal of Chemistry","volume":"66 3","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ijch.70019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148083812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their success in antiviral, anticancer, and antidiabetic therapy is not immediatly apparent, as they have long been considered challenging building blocks. On the one hand, their high density of stereocenters and evolutionarily shaped conformations make them ideal targets for drug development. On the other hand, this promiose is counterbalanced by challenges in synthesis stability, and pharmacokinetics. In this review, we examine how advances in synthetic strategies have accelerated carbohydrate drug development. We discuss successful drug candidates that exemplify strategic design principles, such as the prodrug concept, late-stage functionalization, and the formation of more stable metabolites (for example, C-glycosides). We highlight how these approaches were optimized for effective medicines, considering both industrial-scale manufacturing routes and academic innovations. Finally, we link synthetic methods to clinical translation by summarizing therapeutic potential and relevant clinical trials.</p>","PeriodicalId":14686,"journal":{"name":"Israel Journal of Chemistry","volume":"66 3","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ijch.70017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148083816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
