To synthesize a spherulitic metal-organic framework with a chemically addressable tetrazine core and achieve primary-structure post-synthetic functionalization without altering its hierarchical superstructure.
Synthesized zinc-based MOF JUK-74 featuring a MOF-74-type topology and a tetrazine core.
Performed post-synthetic modification via inverse electron-demand Diels-Alder (iEDDA) click chemistry to introduce pendant primary amine groups.
Evaluated structural integrity, chemical distribution, and porosity using spectroscopic, microscopic, gas sorption, and isosteric heat analyses.
iEDDA functionalization proceeded efficiently throughout the material volume while completely preserving the hyper-branched spherulitic morphology.
The modified framework retained an accessible porous architecture across the functionalized volume.
Introduced primary amine groups exerted a constrained influence on low-loading carbon dioxide adsorption.
