To ensure these characteristics, in the present study, an unsymmetrical bifunctional ligand incorporating both carboxylic acid and hydroxamic acid groups was employed for MOF [Zn(CBHA)](DMF) [SUM-13; CPHA = 4-carboxyphenylhydroxamate, DMF = N,N-dimethylformamide] design and synthesis. Though coupled with Zn2+, which does not typically yield kinetically robust MOFs with hard acids, the SUM-13 featuring differentiated coordination modes of chelating, bridging and monodentate bonding exhibited exceptional chemical stability and permanent porosity, with a Brunauer\u2013Emmett\u2013Teller (BET) surface area of 296.9 m2\/g and a total pore volume of 0.1196 cm3\/g. Additionally, with porosity and open metal sites at the five-coordinate Zn2+ centers, SUM-13 was demonstrated to be an eligible iodine adsorbent, reaching a maximum uptake of 796 mg\/g. These findings underscore the validity and potential of the design strategy in constructing stable metal\u2013organic frameworks.<\/jats:p>","DOI":"10.3390\/sym16081049","type":"journal-article","created":{"date-parts":[[2024,8,15]],"date-time":"2024-08-15T03:49:36Z","timestamp":1723693776000},"page":"1049","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["A Robust Zn-Hydroxamate Metal\u2013Organic Framework Constructed from an Unsymmetrical Ligand for Iodine Capture"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3292-7698","authenticated-orcid":false,"given":"Ting","family":"Song","sequence":"first","affiliation":[{"name":"School of Chemical Engineering, Sichuan University, Chengdu 610065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yinning","family":"Zhu","sequence":"additional","affiliation":[{"name":"Sichuan University Pittsburgh Institute, Sichuan University, Chengdu 610207, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhehao","family":"Li","sequence":"additional","affiliation":[{"name":"Sichuan University Pittsburgh Institute, Sichuan University, Chengdu 610207, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhewei","family":"Mei","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Sichuan University, Chengdu 610065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1168-014X","authenticated-orcid":false,"given":"Zhen-Wu","family":"Shao","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Sichuan University, Chengdu 610065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9780-9062","authenticated-orcid":false,"given":"Chong","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Sichuan University, Chengdu 610065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1126\/science.aaw5304","article-title":"A fresh look at nuclear energy","volume":"363","author":"Parsons","year":"2019","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"928","DOI":"10.1038\/s41560-020-00696-3","article-title":"Differences in carbon emissions reduction between countries pursuing renewable electricity versus nuclear power","volume":"5","author":"Sovacool","year":"2020","journal-title":"Nat.
