{"title":"Scientific Mapping about Detoxification of Chemical Warfare Agents using Porous-Organic-Polymers with Internal Molecular Free Volume","authors":"John Mondal, Chitra Sarkar, Chandan Biswas, Ratul Paul","doi":"10.1039/d5cc00963d","DOIUrl":"https://doi.org/10.1039/d5cc00963d","url":null,"abstract":"Chemical warfare agents (CWA’s) have consistently been a global concern regarding both defence and civilian safety. In order to safeguard people from these harmful chemicals, numerous research teams have collaborated with defence organizations for an advanced technological solution regarding effectiveness and strength. In this context, porous organic polymers (POPs) have been thoroughly investigated as an ideal option for catalytically detoxifying CWA’s by initially capturing them and subsequently transforming them into harmless chemicals. POPs are a new category of porous organic materials primarily made up of organic components linked by robust covalent bonds, resulting in highly interconnected frameworks with firm structures and defined voids for housing guest molecule. This feature article offers a summary of current studies concerning different synthetic methods for POPs (HCPs, PIMs, and certain amorphous POPs), potential modifications to their functionality, and their promising use in photocatalytic/thermal detoxification of chemical warfare agents (CWA’s). This review underscores the need for ongoing research to create effective, safe, and ecofriendly decontamination techniques. Ultimately, various catalytic process of detoxification like hydrolysis, oxidation was explored with POPs and mechanism was established through structure activity relationship with various novel techniques. Additional needs and potential applications of utilizing POPs as nanoreactors for the detoxification of CWA’s have also been discussed.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"149 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building on the elegant review in 2012, this feature article briefly reviews decadal advances in the synthesis and reactivity of Zn–Zn bonded species. We specifically highlight methodological innovations in synthesizing these species, including novel reductant systems, ligand substitution strategies, and zinc hydride dehydrocoupling protocols. A survey of their reactivity is subsequently presented, encompassing heterometallic complex formation, small molecule activation, and catalytic transformations. The elucidation of novel reaction modes, expansion of catalytic frontiers, and exploration of non-classical Zn–Zn bonding configurations represent compelling yet formidable challenges in this domain; thus, concerted research efforts are required in the future.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"93 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While maintaining the crystallinity, porosity, and stability of stoichiometric COFs, these frameworks exhibit enhanced functionality due to their uncondensed sites. These reactive sites not only modulate key structural properties such as charge transport and light absorption but also enable post-synthetic modifications for tailored applications. This review highlights recent advances in the design and synthesis of two-dimensional ss-COFs, emphasizing precise stoichiometric control. Their distinctive properties and potential applications in gas separation, catalysis, and sensing are discussed, along with key challenges and future research directions in this rapidly evolving field.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"109 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
