This architecture enables a rare combination of high\u2010order morphological control and access to a chemically addressable tetrazine core, allowing post\u2010synthetic modification (PSM) at the primary\u2010structure level without loss of the tertiary superstructure. The inverse electron\u2010demand Diels\u2013Alder (iEDDA) reaction provides a fast, mild, chemoselective, and efficient route to introduce pendant primary amines, a functionality that is notoriously difficult to incorporate into MOFs by either pre\u2010synthetic or post\u2010synthetic approaches. Structural, spectroscopic, and microscopic analyses confirm that functionalization proceeds throughout the material volume while the spherulitic morphology remains intact. Gas sorption and isosteric heat measurements further show that the modified framework retains an accessible porous architecture, while the introduced amine groups exert only a constrained influence on low\u2010loading carbon dioxide adsorption. Collectively, these results establish a general strategy for combining hierarchical superstructure formation with precise covalent functionalization in MOFs, opening a route to robust and chemically sophisticated porous materials.<\/jats:p>","DOI":"10.1002\/smll.75464","type":"journal-article","created":{"date-parts":[[2026,8,25]],"date-time":"2026-08-25T12:59:23Z","timestamp":1787662763000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Preserving
